When Bart shakes Homers can of Beer so that it explodes when he opens it.
“That sounded like an explosion at the old Simpson place!” – Lou
“Forget it, that’s two blocks away.” – Chief Wiggum
“Looks like there’s beer coming out of the chimney.” – Lou
“I am proceeding on foot, call in a Code 8.” – Chief Wiggum
“We need pretzels, repeat, pretzels.” – Lou
I forget the name of the episode, but there's one where someone collapses and Marge says "Quick, perform CPR!", which leads Homer to break into a rendition of Bad Moon Rising.
