It's April fools day, and we start off with Homer pranking Bart. Later at the bar, Homer panks Moe, but nobody found it funny, and they ban Homer from the bar and throw him out. Later that night, Homer is still bitter about what happened, so he continues his pranking ways. He prank calls Moe but he gets caught, and Moe is outraged. He grabs his favorite knife and heads out. As Homer is watching tv, Moe bursts through the door and carves his name in Homer's butt.
