"How old after the face lift?" joke

A woman decided to have a face-lift for her birthday. He spends $5,000 and feels really good about the result. On her way home she stops at a newsstand and buys a paper.

Before leaving she says to the sales clerk, "I hope you don't mind me asking, but how old do you think I am?"

"About 35," was the reply.

"I'm actually 47," the woman says happily.

A little while later she goes to McDonald's for lunch and asks the order taker the same question, to which the reply is, "I'd guess that you're 29?"

"Nope, I am actually 47." She's starting to feel really good about herself.

While standing at the bus stop she asks an old man the same question.

He replies, "I am 85 years old and my eyesight is going. But when I was young there was a sure way of telling a woman's age. If I fondle your breasts for ten minutes I will be able to tell your exact age."

As there was no one else around the woman thought what the hell and let him slip his hand down her top.

Ten minutes later the old man says, "OK, it's done. You are 47,"

Stunned the woman says, "That was brilliant! How did you do that?"

The old man replies, "I was behind you in McDonald's".
