Toilet humour

[plonq]

Since the washroom is right next to the coffee room, I dashed in there to take care of some pressing business while I waited for the microwave to finish with my lunch. To my surprise, the stall and both urinals were occupied while a fourth person stood ready to pounce on the first one that came available.

"You'll have to take a number and get in line," he said.
"So," I replied, "even in here I have to mind my pees and queues?"

Nobody appreciates a pun these days.
