A man is sitting at a bar one night, wearing a fancy new watch, covered with buttons and lights and dials.

The woman next to him says, "Wow, that's a really fancy watch.

" Thanks, says the guy, "It's the cutting edge of technology. I can telepathically ask this watch anything I want to know, and it'll answer me, telepathically." "Rubbish, " says the girl. "No, it's true, " says that guy. "Look, tell you what, I'll prove it. I'll ask it if you've got any panties on." The guy scrunches up his eyes for a moment, as if concentrating hard to talk to his watch, then opens them and says, "Nope, it says you haven't got any panties on." "Well, it's wrong, " says the girl, "I do have panties on." "Damn, " says the guy, slapping his watch, "it's an hour fast!"
