New Drink

This guy walks into a bar, sits down and asks the bartender, "Got any specials today?" The bartender replies,  "Yes, as a matter of fact, we have a new drink that was invented by a gynecologist who is a patron of ours. It's a mix of Pabst Blue Ribbon beer and Smirnoff vodka." The guy asks, "Geez, what kind of drink is that?"    The bartender responds, "We call it a Pabst Smir."
