The murderer was an actress and Bumbelo was driving his car onto the movie studio property where they have all those sound stages.
The guard at the gate thought he was bringing in his car for a demolition derby scene and was telling him where to drive to park it with the other stunt vehicles!

Keep watching. You'll come across it eventually.
and keep an eye out for it.
I see what you did there

Ya know, we get this channel which is repeating back to back to back Columbia eps. every day.
I have been recording a few here and there to watch.
I really want to see the one you describe and will start recording all of them and keep an eye out for it.

OMG my favorite scene (can't remember the episode name) was when he took out his wonky glass eye and threw it on the ground to trip up the bungling criminal who was trying to abscond with the jools. Lol and then Columbus also accidentally stepped on his eye when he was going to retrieve it, causing him to fall flat on his back, and his cigar to fly out of his mouth and flip as neat as can be right into his empty eye socket. Then he jumped up and started running around to Benny Hill music with a smoldering cigar jutting from his face as he ran flapping his arms and screaming "HALP ME! HAAAAAAAALP ME!". Oh ho hoooooo, so funny!

Columbo trying to get a vital piece of photographic evidence from a busybody landlady who won't stop talking about all the other pictures in her photo album in the season one episode Suitable for Framing. Mary Wickes was hilarious in that small, yet still memorable role.
You've seen Guy Standeven in something because the man was in everything.

Thoroughly enjoyed Susan Clark's radical transformation from dowdy wallflower to chic clotheshorse in the Lady in Waiting episode.

Another Joyce Van Patten scene that makes me laugh is in "Double Negative", when she plays a nun at a soup kitchen and mistakes Lt. Columbo for a bum. She shakes her head in dismay. "Oh, that coat. That poor old coat." Hilarious
I watched an episode the other day, the one with William Shatner playing a radio talk show host, that had Columbo walk onto the set of a soap opera to talk to a potential suspect. They were shooting a back alley scene with various bums so they assumed he was one of those extras because he blended in with his shabby coat and unkempt appearance.

Pretty much anytime Vera Miles shows up in "Lovely, but Lethal". Miles is hilarious here. A hoot! I really had no idea she had it in her.
Ruth Gordon is also very funny in "Try and Catch Me", but she's always good.
One bit that comes to mind that makes me laugh is in "Old fashioned Murder", where Celeste Holm's character faints upon hearing the word "homicide". Joyce Van Patten's bright response"
See, I told you! She faints!

I'm sure there are others. I like Susan Clark's personality transformation in "Lady in Waiting" when she shows up at the company board meeting in this most inappropriate outfit, decked out in a corduroy pantsuit, in shades of fuchsia and burgundy complete with a train conductor's cap and bill. She's not taking grief from anybody as she turns to her mother and says "in case you haven't noticed it,mother, you're getting old!" Damn! But very funny stuff!

In the art gallery when he thought (pretended to think) the heating grate was a work of art.

The gas station scene in Identity Crisis. Patrick McGoohan must be thinking Columbo's a buffoon - which makes it especially satisfying when that buffoon nabs him.

In Double Shock I love how Colombo keeps messing things up and the housekeeper stays after him whenever he's in the house. It starts with him putting ashes in one of the ashtrays and just escalates from there. Jeanette Nolan plays the housekeeper and in one episode she chases Colombo down the stairs while yelling at him about something else he's done. It's not my favorite episode but Nolan was absolutely wonderful in the part of the housekeeper.

Yeah, that scene was hilarious!

A bird in the hand episode. When Columbo makes Delores watch the car explode on the video, then asks her if she noticed anything unusual. Then her response.

I think the funniest Columbo moment comes from Suitable in Framing when he is with the landlady. And she takes out her photo album and starts talking about her family pictures, just the look on Columbo's face is too much!
"Kaplan. Mr. George Kaplan?"

there's an episode,c an't remember which one, where Columbo goes to a homeless shelter and a nun mistakes him for one of the homeless, offers him some soup or something.
Out of so many funny bits, that is the one that always comes to mind.
You asked a pretty question; I've given you the ugly answer.

Speaking of Dog in
Negative Reaction
, he asks the big, nationally-acclaimed photographer if he thinks Columbo's dog would like pin-up photos of another dog.
Another one, not LOL funny, but in
A Deadly State of Mind
, the murderer glances out a window and sees, across the parking lot, his car's tires being closely examined by the Lieutenant. Then Columbo stands up this little rain-coated figure way off in the distance and a single satisfied teensy-weensy puff of smoke comes off his cigar.

If Ruth Gordon could upstage Clint Eastwood, Peter Falk had no chance!

One of my favorites is Columbo with the doughnut vs. the waitress (a very young Jamie Leigh Curtis). "Did you buy that here?!" ~ The Bye-Bye Sky High I.Q. Murder Case
Another is Columbo seeking a meeting with Mariette Hartley~while she's taking a belly dance class. ~ Try and Catch Me
I love seeing Ruth Gordon and Peter Falk competing for the camera in that same episode. She's one of the very few who could threaten to upstage him!
Actually, there are so many funny moments. I agree about the coat bit when he's mistaken for a homeless man. Columbo and Dog also give us some wonderful scenes, including when he's dangling from a branch with Dog barking at him in "Forgotten Lady".

I like the new haircut he gets in Old Fashioned Murder.

The one where the murder was on that sail boat And he ended up rowing that rowboat across the lake to meet his wife for lunch.

Columbo looking at the book of erotic art in the bookstore, in "The Conspirators."

There are so many hilarious moments throughout Columbo that it is hard to pick a favourite. One weird moment I did notice though was the fountain at the beginning of one episode. Looked so strange I had to rewind to make sure I wasn't imagining it. Fans of Columbo will know or work out which episode I mean. Is at the very start so will not take you too long. But when I think of Columbo I always remember the tennis ball (hot dog sausage) machine, the poison marmalade and those HUGE teeth on the lady shop owner near the lake house. If her brain was the same size she might have survived.

"Now you see him" is on MeTV and it's the one where his wife got him a new coat and he keeps leaving it behind and the other detective keeps bringing it to him.
