A young man excitedly tells his mother he's fallen in love and that he is going to get married. He says, "Just for fun, Ma, I'm going to bring over 3 women and you try and guess which one I'm going to marry." The mother agrees.
The next day, he brings three beautiful women into the house and sits them down on the couch and they chat for a while.
He then says, "Okay, Ma, guess which one I'm going to marry."
She immediately replies, "The one on the right."
''That's amazing, Ma. You're right. How did you know?"
The mother replies, "I didn't like her!"
One day at the rest home, an old man and woman are talking. Out of nowhere the woman says, "I can guess your age."
The man doesn't believe her, but tells her to go ahead and try.
"Pull down your pants," she says.
He doesn't understand but does it anyway. She inspects his rear end for a few minutes and then says, "You're 84 years old."
"That's amazing," the man says. "How did you know?"
"You told me yesterday."
