A cowboy walks into a bar and takes a seat next to an attractive lady. He gives her a quick glance then casually looks at his watch.
The woman notices and asks, 'Is your date running late?'
'No', he replies, 'I just got this new state-of the-art watch and I was testing it.'
The intrigued woman says, 'A state-of-the-art watch? What's special about it?'
The cowboy explains, 'It emits alpha waves and communicates with me telepathically.'
The lady asks, 'Well what's it telling you now?'
'It says you're not wearing any panties.'
The woman laughs and replies 'Well it must be broken because I AM wearing panties!';
The cowboy taps his watch and exclaims, 'Well I'll be damned! This thing's an hour fast!'

Now that is a good one.

I believe I know him
