Joe stopped at a bar to relax after a hard day's work.
The guy next to him ordered a shot and a beer.
He drank the shot, chased it with the beer and then looked into his shirt pocket.
He did this a few times before Joe's curiosity got the better of him.
He leaned over to the guy and said,
"Excuse me. I've been watching your ritual.
Why do you look into your shirt pocket every time you drink your shot and beer?"
"There's a photo of my wife in there," the man said.
"When she starts lookin' good, I'm headin' home!"
