What's the difference between a Bush and a tree?
Wait. I know this one. Ummm, lemmi see. Oh yeah.
A tree grows out of the ground, releases oxygen into our world, looks cool and is great for climbing. It's made of wood (so might be a witch), environmentalists love them and they make excellent pets. Whereas a bush is a spokeperson for the new world order on a par with the Nazi's. Is intellectually challenged (or stupid to the point of ridiculous), greedy with other people's homelands and guilty of a back-catlogue of war crimes...
