The Telepathic Watch!
A rather confident man walks into a bar and takes a seat next to a very attractive woman. He gives her a quick glance, then casually looks at his watch for a moment.
The woman notices this and asks, "Is your date running late?"
"No", he replies, "I just bought this state-of-the-art watch and I was just testing it."
The intrigued woman says, "A state-of-the-art watch? What's so special about it?"
"It uses alpha waves to telepathically talk to me," he explains.
"Oh really? What's it telling you now?" she inquires.
"Well, it says you're not wearing any panties..."
The woman giggles and replies, "Well it must be broken then, because I am wearing panties!"
And the man starts tapping on the watch face and says,
"Damn thing must be an hour fast!"
