An airline pilot walks into a airport pub at LAX, spies a beautiful brunette sitting alone at the bar and approaches on her right side. He places his left hand on the bar so she can clearly see his expensive watch.
"Like my watch?" he asks. "It uses special crystals to tell me things about people."
"Oh, really?" says the brunette, clearly unimpressed. "What does it tell you about me?"
"You're not wearing any underwear," he replies.
"I think you better return your watch," she chuckles, "because I am wearing underwear."
"What?" he says, looking down at his watch. "Ah. It's still on Denver time."
