A Fifteen Please

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 drink. In walks a blonde. “I’d like a Fifteen, please.”

“What the HELL is a fifteen?”

“Seven and seven, Duh!”
