Martini Madness

A businessman enters a tavern, sits down at the bar and orders a double martini on the rocks. After he finishes his drink, he peeks inside his shirt pocket and asks the bartender for another double martini.

After he finishes his second drink, he again peeks inside his shirt pocket and asks the bartender to bring another double martini.

The bartender says, "Look, I'll bring you martinis all night, but you gotta tell me why you look inside your shirt pocket every time you order a refill."

The man says, "I'm peeking at a photo of my wife.
When she starts to look good, then I know it's time to go home."
