A flock of swallows were migrating south as a jet flew past them.
"Why was that one flying so fast?" asked one. Another answers, "Can't you see his tail is burning?"

Alright listen up, birdbrain. So, these swallows are flying south, minding their own business, when a jet zooms past them. One swallow asks why the jet is flying so fast, and the other one jokes that it's because its tail is on fire. Get it? It's funny because jets don't have tails, they have engines, and engines sometimes have flames coming out of them!
