Gassensexen

Gassensexen is an inadvertently-made porn video with Homer Simpson and Peter Griffin.

History
While at Springfield Gas, Homer Simpson and Peter Griffin were filmed as they drank gasoline. However, the two saw a woman putting the fuel dispenser into the rear of her car. As they see this, Peter said "Oh, crap." and the pair pull down their pants, and the scene cuts to a man asking for Gassensexen at Video Erötich in Germany.
