Blonde in a Bar

A redhead walks into a bar. She walks up to the bartender and says, "I'd like a RW, please."


The bartender says, "What's a RW, might I inquire?"


"Red Wine, Duh!"


The bartender serves her her drink. A brunette walks into the bar. "I'd like a WW, please."


"A WW is... what?"


"White Wine, Duh!"


Bartender serves her _her_ drink. In walks a blonde. "I'd like a Fifteen, please."


"What the HELL is a fifteen?"


"Seven and seven, Duh!"
