Carl: Damn, Lois just took a shot of everclear and chased it with a beer.

Get the designer drunk mug.
Someone who is not so drunk that they can call an Uber or Lift driver or taxi driver, and who has the means of paying for the driver.
Anne will be the designated drunk driver since she has an Uber of Lift app on her I phone and never is so drunk or poor that she can't call and pay for one. Also Anne would never leave any of us behind, or anyone drunk with the keys to a car.
