the facelift

A man decided to have a face lift for his birthday. He spends 4,000 grand and feels really good about the result. On his way home he stops at a newsstand, buys a paper and says to the sales clerk, "I hope you don't mind me asking, but how old do you think I am?"

"About 34," was the reply.
"I'm actually 46," says the man happily.

About a while later he went for lunch to McDonald's and asks the order taker the same question, to which the reply is, "I'm guessing that you're about 30?"
"Nope, I am actually 46." He's starting to feel really good about himself.

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 poor. But when I was young there was a sure way of telling a man's age. If I put my hand down your pants and play with your p*nis for ten minutes I will be able to tell your exact age."

As there was no one else 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. I know you're 46"
Stunned, the man says, "That was brilliant! How did you do that?"
The old lady replies, "I was behind you at McDonald's".
