Marlene's Random Questions

I'm bored so I'm gonna ask some random questions. Why do cows go moo? Where did the idea of jelly beans come from? Why are fish slimy? Is it possible to lick your elbow? Is it true that when you lick your elbow you turn into the opposite gender? Why are lemons sour? Why are potatoes lumpy? Do we as people smell but we don't know it? Why are pineapples pokie? Why do animals have whiskers? Why does tofu wobble? That is all I can think of right now eventually I will come up with new questions. The elbow thing kinda creeps me out and gives me goosebumps.
