There's plenty of room for humor in politics, God knows, but... - Al Franken

"Mistakes are a part of being human. Precious life lessons that can only be learned the hard way. Unless it's a fatal mistake, which, at least, others can learn from."

"Bob Dole used to be really funny. Barney Frank can be kind of funny. Bob Kerrey has a good sense of humor."

"There is - I mean - I found early in life that righteous indignation is a little off-putting, and so I try to couch it with humor."

"If you look at terrorists, they really have no sense of humor."

"Humor and seriousness are not in opposition to each other."
