So I was sitting on the bus just reading a book when somebody tapped me on the shoulder.

I turned around and saw an old lady. She said to me, "Sonny, would you like some nuts? I've got a couple hazelnuts and almonds if you'd like."

"Sure.", I replied. Then she gave me a handful of nuts and went back to sit with her friends.

"What a nice lady", I thought, while happily munching on the nuts.

A few minutes later, I felt another tap on my shoulder and there she was again, offering some nuts. I gladly accepted and she went back to her seat.

After about 10 minutes, she tapped me on the shoulder, once again offering some nuts.

I asked her, "Why don't you eat them yourself?"

"Because we've got no teeth", she replied.

"Then why do you buy them?", I asked.

"Oh, because we just love the chocolate around them."
