I Am The Walrus

"I Am the Walrus" is a song by The Beatles released as the b-side to 1967's "Hello Goodbye". It is known for its bizarre (apparently meaningless) lyrics.

Aluminum Siding
In Aluminum Siding, it was stated that if "I Am the Walrus" was played while operating an automobile, it would cause the vehicle to behave erratically and uncontrollably, and finally crash in a violant explosion.

This anomaly was the center of the pilot episode, "Drive Me Crazy."

In "UFOs Over Wacovia", the jinx was shown to effect spacecraft when it was used to down an alien spaceship.

Meta-info
The joke was one of the many non-sequiturs that Aluminum Siding relied on. Its origins can be traced to an even earlier show produced by Lotz, which had that a character who was driving poorly would always sing the song; not that the song caused the bad driving.
