Beast Boy's Flying Ability

Okay, so listen up, smarty pants. The joke is that Beast Boy is good at flying because Terra (get it, like the Earth) hasn't forgiven him, so gravity is not affecting him. It's funny because it plays on words and assumes you know a thing or two about comic books. You probably don't, but that's okay. Some people peak in high school, and you, my friend, peaked before you even learned to read.
