A cowboy walks into a bar and sits next to a beautiful woman. He gives her a quick glance then causally looks at his watch for a moment.

The woman notices this and asks, “Is your date running late?”
“No”, he replies, “I just got 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?”

The cowboy explains, “It uses alpha waves to talk to me telepathically.”

The lady says, “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 because I am wearing panties!”

The cowboy smiles, taps his watch and says, “Damn thing’s an hour fast.”
