A man is sitting at a bar in Cape Town and looks at his watch several times in the space of a few minutes.
The woman sitting nearby notices this and asks, "Is your date running late?"
"No," he replies, "I have this state-of-the-art watch. I was just testing it."
The intrigued woman says, "A state-of-the-art watch? What's so special about it?"
The man 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 man smiles, taps his watch and says, "Bloody thing's running about an hour fast, can I buy you a drink in the meantime?"
