A brash young man strolls into a bar and takes a seat next to a stunningly attractive woman. He gives her a quick glance, then casually looks at his watch for a moment.

The woman notices this and asks, 'Your date running late?'

'No, no...', he replies, 'I just bought this state-of-the-art watch and I was just testing it.'

The woman, intrigued, asks: 'Wow! A state-of-the-art watch? So, what's special about it?'

'Well, it uses ultrasonic waves to telepathically talk to me,' he explains.

'Interesting...so what's it telling you now?'

'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 explains, 'Damn thing must be an hour fast!'
