A Mug for Grammar

A bit stuck for Blinspiration this evening until I was making a cuppa and came across this mug, given to me by a friend last year.

Now I will admit to being very keen on the correct use of english, grammatical accuracy and generally a bit of a pedant, but I am nowhere near as furiously puritanical as the designer of this! (Although I do have a sneaky admiration for their expletively expressed teaching approach!)

p.s. there's more on the other side, sorry I can't do 3D yet!
