The Alpha Wave 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.

- What's it telling you now? - she asked.

- Well, it says you're not wearing any panties. - he said.

The woman giggles and replies:

- Well it must be broken then because I am wearing panties!

The man explains:

- Damn thing must be an hour fast.
