"I'm actually 47," the man says, feeling really happy.
After that he goes into McDonalds for lunch, and asks the order taker the same question, to which the reply is, "Oh you look about 29".
"I am actually 47!" This makes him feel really good.
While standing at the bus stop he asks an old woman the same question. She replies, "I am 85 years old and my eyesight is going. But when I was young there was a sure way of telling a man's age. If I put my hand down your pants for ten minutes I will be able to tell your exact age."
As there was no one around, the man thought what the hell and let her slip her hand down his pants. Ten minutes later the old lady says, "OK, it's done. You are 47."
Stunned the man says, "That was brilliant! How did you do that?"
The old lady replies, "I was in line behind you at McDonalds."
