Found on a web forum. Probably as old as the internet.
A man walks into a bar, notices there’s no women in there, figures it’s a gay bar but he wants a beer too much to care. So he goes up to the bartender and asks for a beer.
The bartender says “What’s the name of your penis?”
The man replies “I haven’t given my penis a name.”
The bartender says “Better give it one if you want a beer” and walks away.
The man nudges the customer to his right and asks “Uh, um, uh, what’s the name of your, um, uh, penis?”
The customer gleefully replies “Timex! Takes a lickin… keeps on tickin!”
The man, now slightly disturbed, asks the same of the customer to his left.
The customer replies “Foooooord! Have you driven a Foooooord lately?”
The man thinks for a moment, then motions to the bartender.
The bartender asks “So, what’s the name of your penis?”
The man replies “Secret. Strong enough for a man; made for a woman.”
