Old and New Jokes

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, thats a really fancy watch.”
“Thanks, says the guy, “Its the cutting edge of technology. I can telepathically ask this watch anything I want to know, and itll answer me, telepathically.”
“Rubbish, youre having me on,” says the girl.
“No, its true,” says that guy. “Look, tell you what, Ill prove it. Ill ask it if youve 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 havent got any panties on.”
“Well, its wrong,” says the girl, “I do have panties on.”
”Damn,” says the guy, slapping his watch, “its an hour fast!”
