What's the difference between a fly and a bird?
A bird can fly, but a fly cannot bird.
Hey, listen up, buttercup. The joke is all about how a bird can "fly" (as in move through the air), but a fly can't "bird" (as in, do the things a bird does). It's funny 'cause they use the same word in two different ways. Simple enough for ya, genius?
