A brunette, redhead and blonde went into a bar. The brunette ordered a "ML" the bartender said, "What's an "ML"? She answered, "A Miller Light, dah." The redhead then ordered a "BL" and the bartender asked the same question and was told, "A Bud Light, dah." Exasperated now for being made fun of twice he asks the blonde what she's going to have. She says, "I think I'll have a 15." Very disgustedly, the bartender says, "And what the hell is that?" She answers, "A 7-7, dah."
