One day a Blonde, a Brunette and a Redhead walk into a bar. The Brunette says "I'll have a BL." The bartender asks "What's a BL?" "A Bud Lite, DUH!" answered the Brunette in a snotty tone. The Redhead says "I'll have a ML." "What's a ML?" asked the bartender. "A Miller Lite, DUH!" answered the Redhead as if she was talking to a mentally challenged person. Then the Blonde says "I'll have a 15." Now the bartender knows what is happening and says "Oh, I get it the BL is the Bud Lite and the ML is the Miller Lite, but what is a 15?" The Blonde answers, "A seven and seven, DUH!"
