He decides to stop and get lunch, and after placing his order, he can't help but ask the girl behind the counter "How old do I look?" The girl takes a close look and says "I would say about 32". The man says happily "Why, thank you, I'm 47!"

Feeling VERY good about the expensive surgery, he whistles as he walks to the bus stop. Seeing an old woman waiting on the bus bench, he asks "How old do I look to you?" The woman says "Well, sonny, I can tell you exactly how old you are if you let me put my hand down your pants for ten minutes."

He says "That's impossible!", but the woman insists that ten minutes with her hand down his pants will prove her point. The man looks around, and seeing no one close by, he agrees. The old woman reaches into his pants.

After ten minutes, she withdraws her hand and he says "Okay, how old do you think I am?" The old woman smiles and says "You're 47".

"Oh my God!" the man says, "how did you know that?"

"It was easy", she says, "I was behind you in line at McDonald's."
