All I could think of between 'rictus of pleasure' and 'boxcutter' was

"Why so serious?"

But seriously, I'm only off tomorrow myself by dint of pure technicality. If Mondays were one of the days I'd agreed to work, I'd be there, slapping meat on bread for people to stuff in their food holes.

I like to think of this shitty job as purgatory, or even a crucible. I have to put up with this crap for a bit longer, and then academia becomes my #1 occupation.

Good luck, and try not to give anyone a Cheshire grin tomorrow.
