History's greatest bullies?

In the wake of Washington Post columnist Richard Cohen calling satirist Stephen Colbert "a bully," Jon and I started wondering: is Colbert the biggest bully in history? Probably. But being believers in the democratic process, we decided to assemble a list and leave the choice to you. 1. Charlie Chaplin attacks a defenseless Hitler (1937) Anybody who's ever seen "The Great Dictator" knows that it's Chaplin with the problem. And the "comedian" made money off it, which shows you what he was really interested in. 2. Rich Little does impressions of Richard M. Nixon at a time when the President was really going through a lot (1974) This card-carrying Canadian must've really hurt the President's self-esteem. Talk about kicking a guy when he's down--I guess that's considered "manly" up north. 3. Vaughn Meader brutally spoofs JFK (1961-1963) Not content with nearly driving President Kennedy out of politics ("I just can't take it anymore") this jerk made fun of the whole family--even, if memory serves, the retarded sister. I bet he liked it when Kennedy got shot. 4. Mark Russell writes a symphony of pure hate (1979-present) No one is safe from Russell, who seems determined to bring down anyone more successful than himself. Like so many of history's greatest scoundrels, the openly sociopathic Russell puts his attacks to music, so you remember them better. And the worst thing of all: he uses your tax dollars to do it!
