Confident man

A rather confident man walks into a bar and grabs a stool next to a gorgeous 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 am 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.

What's it telling you now? she asks.
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!
The man gasps and taps his watch, Damn thing must be an hour fast.
