No love for Phil LaMarr's Sidney Poitier impression?

Nicole Sullivan as Britney Spears and LeAnn Rimes ("Yodelay! Yodelay! Yodelay!"). Also, the glamor girl in "Pretty White Kids with Problems."

Debra Wilson's Oprah Winfrey.
Respect what you have

Nothing beats Deborah Wilson's Oprah and Whitney sketches. Some of the funniest celebrity impersonations I have seen.

Pat Kilbane's Howard Stern. I honestly thought it was really Stern when he first did the impression.

Debra Wilson: Oprah, Whitney
Pat Kilbane: Howard Stern
Alex Bornstein: Rosie O'Donnel & Regis
Mary Scheer: Barbara Streisand
Nicole Sullivan: Dru Barrymore
Mo Collins: Madonna & Martha Stewart
Phil Lamarr: Michael Jackson & Prince
Aries Speers: Eddie Murphy
Will Sasso: Pretty much all his celeb impressions were spot on.
Frank Caliendo: Rod Roddy, John Madden and Robin Williams
Stephanie Weir: Anna Nicole
Nicole Parker: Ellen

Pat Kilbane as Charlton Heston. There was a sketch where he played all the roles in a film and I loved that sketch.

Will Sasso - Louie Anderson
Frank Caliendo - John Madden
Debra Wilson - Oprah
Alex Borstein - Rosie O'Donnell
Aries Spears - Shaq

Will Sasso as Stone Cold Steve Austin , Sasso even did this impression on a Monday Night Raw wrestling show

LaMarr as Michael Jackson, pretty spooky good

I can't believe none of you mentioned Andrew Bowen's name. ONCE. He was the best actor in the entire show!!
Instead, you praise Bobby Lee, a person who can't act! UGH!!!!

Debra Wilson's Whitney Houston and Oprah Impression (Add Ares Spears impression of Bobby Brown and you have comedic gold.)
Will Sasso's Steven Segal, Arnold Shwartzenegger (I don't know how to spell his name,) Robert Deniro.
Frank Caliendo as John Madden and president Bush (Again, add Michael's John Kerry impression and you have comedy goldagain!)
I get it up, I get it up in the dark, I make her feel I'm not a holy man

Debra Wilson as Whitney Houston
Mo Collins as Diane Sawyer.

Good ones, guys. Keep them coming.
Ron Pederson as Jimmy Fallon
Frank Caliendo as Robert David Hall from CSI
Nicole Parker as Hilary Swank
Keep in mind that when I said "best celebrity impressions", I meant the ones you literally thought were the real people guest starring for the first minute. For example, Frank Caliendo's GWB was amazingly accurate, but just from the face you could clearly see that it wasn't actually Bush. Same goes for most of Bobby Lee's characters.

Frank Caliendo as George W. Bush
Michael McDonald as John Kerry, and the angry Persian cab driver guy
Debra Wilson as Oprah
Bobby Lee as Connie Chung, that geek from American Idol, the screwy North Korean dictator, ANY friggin Asian out there. dam the dude is funny
Good times good times
Try not. Do or do not. There is no try.

I forgot about Kilbane's Stern. I ALWAYS thought Stern was guest-starring when he did it!
I feel sorry for today's generation of kids. They didn't have Hey Arnold!

Pat Kilbane as Howard Stern

Debra wilson as Oprah
(Classic, ultimate spot-on impression. No other Oprah impressionist comes close.)
Nicole Parker as Ellen DeGeneres, Britney Spears, James Blunt(!) and Judy Garland
(Hers is the only Ellen impersenation I've ever seen/heard and it's so well-done considering Ellen's style is kinda difficult to pull of. She also does a way more realistic, more amiable version of Britney compared to your average Britney impersenation. And it works. And her Judy Garland/Dorothy is justwow. The best thing about all her impersenations is she actually physically resembles all those people to a certain extent.)
Stephanie Weir as Anna Nicole Smith
(Another super-accurate imperession. You could watch those ANS skits over and over again and Weir would always make you laugh.)
Will Sasso as Steven Seagal and James Lipton
(I never got a chance to watch most of the older MadTV skits but I've seen some. (Yeah, I know I missed out on a lot) I know Sasso did a lot of dead-on impressions but Sasso's Seagal is really a classic. And I like Sasso's Lipton impression a lot more than Will Ferrel's on SNL.)
Keegan Micheal Key as Snoop Dog and Barack Obama
Bobby Lee as Connie Chung
Alex Bornstein as Rosie O'Donnell
Frank Caliendo as Jay Leno
Ike Barinholtz as Dane Cook

Josh Meyers' Matthew Mcconaughey.
Absolutely dead on perfect. I thought the real Matthew was guest starring when I saw him.

I think Phil LaMarr was a pretty good impressionist, although he didn't do alot, but the Sass pwns all. Pretty much every impression he did was great.

Will Sasso's Arnold
Aries Spears's Eddie Murphy and Bill Cosby
And I don't know who played Tom Hanks in Gump Fiction, but that was great.
