A man's wife asks him to go to the store to buy her cigarettes. He walks there only to find it closed. So, he goes into a nearby bar to use their vending machine.
At the bar he sees a beautiful woman and starts talking to her. They have a couple of beers and eventually end up in her apartment. After they've had some fun, he realizes it's 3 a.m. and says, "My wife's going to kill me. Do you have any talcum powder?"
The woman gives him some talcum powder, which he rubs on his hands and then goes home.
His wife is waiting for him in the doorway and screeches, "Where the hell have you been?!?!"
"Well, honey, it's like this. I went to the store like you asked, but they were closed. So I went to the bar to use the vending machine. I saw this great looking chick there, we had a few drinks, one thing led to another, and I ended up in bed with her."
"Oh yeah? Let me see your hands!"
She sees his hands are covered with powder and says, "You liar! You went bowling again!"
