Fast Watch

A rather confident young man walks into a bar and takes a seat next to a very attractive young 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 testing it."
Intrigued, the 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.
"What's it telling you now?"
"Well, it says that you're not wearing any panties..."
The woman giggles and replies, "Well it must be broken then, because I am wearing panties!"
The man exclaims, "Damn! - this thing must be an hour fast!"
