Paddy walks into a bar. There's nobody there except the bartender and a beautiful woman sitting at the other end of the bar.
The man says, "I'm buying that woman a drink." The bartender says, "You don't want to do that. She's a lesbian." The man says, "I don't care, give the drink."
After the woman gets the drink, she raises the glass to her benefactor. The man strolls over to her. He says, "Hi. I'm Paddy from Dublin, Ireland. So how are things in Lesbia these days?"
