This host on American TV will say goodbye to you using what he calls a "Guffaw". Can you describe it? Who is he?

From Wikipedia:

Mandel has a signature sign-off on Deal or No Deal: starting with his right hand in a salute position, he waves in a circular motion away from his face while twisting his wrist, as the crane shot typically pulls out and the show fades out. Howie calls this a "guffaw," and introduced it in his standup early in his career.

I never really liked him until he went bald. Maybe it was the characters he played, but he seemed too "kiddy". And I love mysophobes too. OCD rocks!

That's right , good answer VV, W
