The “MUG!” is a cute porcelain mug with a knuckle duster for a handle. It’s £12, plus shipping. (That’s a lot of cash for a mug. I say wait until this shows up at your local Spenser’s Gifts, provided those stores are still in business.)

If you want the real deal, bang for your mug, pack a punch mug, check out the Mohamed Ali of knuckle buster’s, or as they say on this side of the pond; brass knuckles, check this gold standard……….

I’d smash a coworker in the face with this mug at some point, I’m sure of it.
