That one guy who was on Comedy central who had this funny sweaky voice, and he was big, the last name was Iglesias, but I can't remember the first name
Bob Saget is pretty good in stand up, he's fuckin raunchy
Eddie Izzard
Ellen Degeneras
Richard Pryor
Martin Lawrence
Jimmy Carr
and so many more I can't think of at the moment

just watch comedy central on friday nights for the stand up, they always have someone pretty damn funny on there
