Dumb Blonde Joke No.48

One day a Blonde, a Brunette and a Redhead walk into a bar. The Brunette say's "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 say's "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 say's "I'll have a 15" Now the bartender knows what is happening and say's "Oh I get it the BL is the Bud Lite and the ML is the Miller Lite but what is a 15?" The Blonde answer's "A seven and seven, DUH!"
