Look at the pain the bunch of twats are inflicting on this poor bloke, illustrated with annoyance by artist David Shrigley. 
 
Nothing like a bit of passive aggressive shade in the form of stoneware to convey your feelings towards your coworkers. If you’re sipping on this MUG-nificent Bunch of Twats Mug next time you’re in the office and Karen gets offended, remind them it's just a joke! And when their back is turned, lift the said mug, squint your eyes and take a long, slow drink of bitterness... 
 
Bringing this mug into the office is also a handy way to check how strong your work's HR policies are - thanks for that, Shrigley!
