This is the Critical Hit D20 Mug available for $13 from ThinkGeek. It holds 12-ounces and even comes with a lid so coworkers will have a harder time smelling the booze I pour into my coffee because I can't stand this place and it's the only thing that helps get me through the day (besides my two hours after-lunch nap in a bathroom stall). I don't take kindly to nosy coworkers getting all up in my business and accusing me of drinking on the job. You know what happened to the last person who accused me of drinking on the job? He fired me.
One more shot with the lid on after the jump.
Thanks to CJ, who drinks directly from the coffee pot when nobody is looking.
