From Ernie:
A woman decides to have a facelift for her 50th birthday. She spends £15,000 and feels pretty good about the results. On her way home, she stops at a news stand to buy a newspaper.
Before leaving, she says to the clerk, ‘I hope you don’t mind my asking, but how old do you think I am?’
‘About 32,’ is the reply.’
‘Nope! I’m exactly 50,’ the woman says happily.
A little while later she goes into McDonald’s and asks the counter girl the very same question.
The girl replies, ‘I’d guess about 29.’
The woman replies with a big smile, ‘Nope, I’m 50.’
Now she’s feeling really good about herself.  She stops in a drug store on her way down the street. She goes up to the counter to get some mints and asks the clerk this burning question.
The clerk responds, ‘Oh, I’d say 30.’
Again she proudly responds, ‘I’m 50, but thank you!’
While waiting for the bus to go home, she asks an old man waiting next to her the same question.
He replies, ‘Lady, I’m 78 and my eyesight is going.  Although, when I was young there was a sure-fire way to tell how old a woman was. It sounds very forward, but it requires you to let me put my hands under your bra.
Then, and only then can I tell you EXACTLY how old you are.’ They wait in silence on the empty street until her curiosity gets the best of her.
She finally blurts out, ‘What the hell, go ahead.’
He slips both of his hands under her blouse and begins to feel around very slowly and carefully…
He bounces and weighs each breast and he gently pinches each nipple. He pushes her breasts together and rubs them against each other.? After a couple of minutes of this, she says, ‘Okay, okay….How old am I?’
He completes one last squeeze of her breasts, removes his hands, and says, ‘Madam, you are 50.’
