A brunette, a redhead, and a blonde walk into a bar. To keep it brief, each orders her drink using an abbreviated code.
The brunette approaches the bartender and says, "Hey, give me an ML." The bartender nods and hands her a Miller Lite.
Next, the redhead walks up and says, "I'd like a BL." With a nod, the bartender serves her a Bud Lite.
Finally, the blonde steps forward and says, "Give me a Fifteen."
"A Fifteen?" the bartender replies, puzzled. "What the hell is that?"
"Oh, you know," the blonde says, "A Seven and Seven."
