Not only does he have to use both hands in a rhythm, he also delivers his lines to the person's chest (this can last at least 30 seconds) and looks up to make eye contact at the last few words.
It has got the point, I can't help noticing the hands and the line delivery. So now I tend to look away from the screen when he speaks. And the hair, don't get me started it's something middle aged men do to hide the fact they're thinning on top. It looks ridiculous. Unless you're in a Grease remake!

like father, like son
With the only difference that the father is an actor.

Two reasons I think
1)His father's influence (like father, like son).
2)His father studied with Sanford Meisner , so I think you're seeing one aspect of the Meisner technique. I notice that all the actors that studied with him tend to do that.

At least he has a television show. Your claim to fame is begging for attention by dumping on random actors on the internet. Bravo.
Time flies like an arrow. Fruit flies like a banana.

He learned at a very early age that he was going to be shortest person in any crowd and so his arm-waving is an attempt to attract attention.
Look at me, he is screeching with his gestures, I'm down here.

I was going to make a joke about you looking at his hips until I realized exactly what you were talking about. And you're so right!
Personally, I like the way he gestures. Some people just talk that way, so yeah, I'm cool with it.
"I am the Rumble Suppressor."

He makes wild gestures with his hands and heaps his hair on the top of his head because he can't act and he's a squirt.

I came here to post the same thing. He also moves his hips like Jack Sparrow

It's a mannerism that I happen to like! Along with that ass!

Scott inherited a lot of his father from the hot headedness to the aggression (which the double hand mobility dictates). The only thing I think Scott doesn't have is his father's voice. Scott's a lot less raspy than good old Jimmy Caan, even when the old man was Santino in the Godfather.

So do some black folksI'm black and I do that half the time, so it's not just a Jewish/Italian thing eitherthat's just how I express myself,plus it's fun as hell to do!

He moves his arms wildly because he can't stop himself which indicates he's very insecure. He also stacks his hair on the top of his head to try to look taller, again, another sign of insecurity. He speaks in "choppy" words which is yet another sign of insecurity. He simply isn't very good and I'm sure if it weren't for his father he wouldn't get work.

Jews and Italians all talk with their hands.
Hence the saying, "If you cut off their hands they wouldn't be able to talk!"
I love it. I think it's the cutest thing. But then again Scott is the finest thing to come down the pike in a long time! Love that Danno!!

i love danno's gestures with steve when he's making a point lol
i was watching one of my favorite oldies 'eldorado'i like it a lot, but somehow i'd never realized that james caan was in itanyway, a few days ago, it was on and my sister said, 'that's james caan'i was amazed at how much his interactions with john wayne looked like scott and alex on h50i totally agree, they do move, talk, and gesture very much alike
ladibug
A woman's heart should be so close to God that a man must seek Him to find her.

It's actually a mannerism that he inherited from his father. Have you ever seen James Caan movies or tv shows? It's actually quite remarkable how alike the two of them speak, walk, move, etc. I don't mind it, it's part of what makes him who he is.

yeah you're right! He's always using his whole body too really. He makes his points very obvious
