A kid is on his lawn, playing with mud. A man walks up to him and asks, ?What are you doing?? The kid says, ?Making a smart potion. Would you like some?? So the man says, ?Sure. I?ll try some.? So the kid gives the man a bit of the mud in a cup to drink. When the man drank it, he yelled, ?Blech! This is mud!? So the kid says, ?See, getting smarter already.?
