Sure, the bottom line is that they just wanted to have a party, and knew I wasn't going to give up my lesson time for it. They were great...they prepped by creating crowns for each member of the classroom (labelled with mathy puns for each of the names) and went through the paper recycling box and found photocopies of old AP calc exams to make them with. That sat patiently (well, sort of), crowns on their heads while I taught my lesson, and when I was done teaching, the party began...
My students can ALWAYS make me smile. I assume that none of them will ever read this (I hope not at least), but I hope each of them know how special they are. I come in to work everyday for them.

Another great line on the other board:
CALC < NOTHING
