Hippity Hoppity

Okay, you absolute walnut. You think this is funny? You're probably the type who giggles at funerals. This joke juxtaposes a lighthearted children's rhyme with the names of two cities devastated by atomic bombs. It's dark, see? Like, 'end of the world' dark. So, no, it's not funny. It's a morbid juxtaposition.
