Adolf Hitler

Adolf Hitler (April 20, 1889 – April 30, 1945) was a fascist Austrian-born German politician, leader of the Nazi party, Führer of Germany (a self-given name meaning "leader" or "guide", used in his role as Chancellor and acting President) from 1933 to 1945. He is often referenced, and occasionally appears, usually in flashbacks or dream sequences.

History
Adolf Hitler is seen in the flashback tracking Bobo's life after Charles Montgomery Burns abandons him. Adolf takes the bear as his own, however when trapped in his bunker at Berlin he blames the bear. Somehow Bobo escapes this bunker. Bart randomly dials Argentina, coincidentally calling Adolf Hitler. He attempts to answer the phone, but does not reach it in time.

Trivia

 * Matt Groening is not very fond of Hitler jokes in The Simpsons, but occasionally he lets a few good ones pass.
