The owner jumps up and walks over to the girl. “You're the 3rd person to enter my bar and I'm going to name it after you.”

“Okay,” she says, “my name is Jill.”

The owner looks her over and says, “I like your legs so I'm going to name the bar 'Jill's Legs'”

The next day a bum is sitting outside the bar and a cop askes him what he's doing. He answers, “Waiting for Jill's Legs to open so I can get a drink!”
