Please forgive me for discussing a gasoline powered automobile on a electric bicycle forum.

A polar bear was driving his car. The car broke. The polar bear was not so good with mechanical stuff so he called a tow truck. While he was waiting for the tow truck to arrive, he walked to a store and bought some ice cream. He ate the ice cream. Because he had no spoon and he was a messy type of bear. He got ice cream all over his face. The polar bear walked back to his car. Tow truck driver who also was a mechanic was looking at what had gone wrong with the car. The mechanic said to the polar bear. "You blew a seal." The polar bear said - "No I didn't, this is ice cream all over my face."
