The Chalk Mug.

You could ask Dindrane nicely to tell you filthy things to scrawl on it in Latin.

You could walk around the office with "FNORD" or "FHTAGN" scrawled on it and see who catches it first.

You could draw a chalk outline of your favorite cartoon character.

You could sit in a meeting and every time a particular person says something, just glare at them and make a new ticky mark on the mug–just to unnerve them.

Or more meeting fun…play tic tac toe on it to pass the time. Or Hangman, even.

The possibilities are endless, really.
