Most likely to

Stephen Colbert is probably going to be most familiar to American readers. I've had questions lately, with the deterioration of, oh, just lots of stuff, whether satire has place anymore as a corrective to social ills. But I think this guy keeps it fresh. There's also something quite nice he does, which is to break character, simply in his facial expression, a few times in the course of his show. It recalls what I like about a few performers who you can imagine at the back of the room in high school, with the teacher saying:

.............Colbert,
"Yes,Mr.Wayans,is there something you'd like to share with the class?"
............Campbell,

They have.

Who's on your list - or were you that person?
