An old lady and an old man are sitting in their retirement home.
The man turns to the woman and says,"I bet you can't tell how old I am."
"Okay," she says,
She then unzips his fly, feels around for a while and finally says, "You're 83."
"That's amazing!" the man exclaims. "How did you know that?" he asks.
"You told me yesterday." She replies.
