A homeless man sits on a subway bench next to a man in a 3-piece suit. Irritated by the intrusion of the "bum," the suit opens his paper and tries to read, but the bum is mumbling over and over, "Looks like a rock, but feels like rubber . . . I'll be damned!"

Irritated again, the suit says, "Are you talking to me?" The bum says, "No, not really---I was just looking at this thing here. It looks like a rock, but it feels like rubber. See?"

Interested, the suit does look, and says finally, "Here, let me see it." The bum hands the item to the suit who holds it to the light and brings it close to his eyes, smells it, and finally says, "You know, you're right---it does resemble a rock but has the texture and consistancy of rubber. Where did you get it?"

"Outta' my nose . . ."
