Shots are key to any unrememberable evening of drinking, but coordinating the two glasses necessary to shoot and chase can be exhausting, and incredibly confusing. Thankfully, sweet Mother of Cuervo, the Quaffer is here.

The Quaffer is an oversized shot glass shaped like a POM bottle. To load, just tilt, and fill the 2.25oz lower bulb with chaser and the 1oz upper bulb with shot. The Q's narrow waist prevents the liquids from mixing, so throwing it back unleashes a potent liquor/chaser one-two that'll have you fighting with oversized bouncers and undersized table lamps in no time.

Some of the lethal Quaffer shots we recommend:

Punta Del Fuego
Bottom chase: Sunkist Orange Soda
Top shot: Cheap Tequila

The Autobahn
Bottom chase: Cream Soda
Top shot: Jager

Redrum
Bottom chase: Mountain Dew Code Red
Top shot: Citrus Rum

The Sophisticato
Bottom chase: Ginger Ale
Top shot: Fernet Branca

There are also monster beer Quaffers available, holding 11oz in the bottom bulb -- perfect for your culturally insensitive car bombing of choice. But either Q will take the guess work out of binge-drinking and, more importantly, prevent you from suffering the indignity of training wheels ever again.
