Nipples

Mads, my Norwegian companion, and I were out the other day, and I noticed when I went to scratch my chest, that my left nipple was extremely hard. It was like a sharp piece of plastic. I asked Mads.

"What?"

"Just feel it and tell me if it's extraordinarily hard."

"What are you talking about? Your nipple's hard?"

"Really hard."

"Do you think it could cut glass?"

"Cut glass?"

"Yeah, like a cat burglar. You could cut those perfect circles in a window, then sneak in."

"Do they do that?"

"The best ones do."

"Wow. No, I don't think it's that sharp. But why would it be hard like that at all?"

"I don't know."

"You don't know?"

"I don't know."
