I take attendance by having students answer a question.
If you were a superhero/villain, what would your catchphrase be?
Halfhearted heroism:
- I tried :P
- I feel like I need to say something but I don't really know (<-- about="" an="" anticlimax...="" li="" talk="">
- You stop that!
- Save me.
- Life is so complicated. (<-- a="" and="" arriving="" at="" chaos="" himself="" i="" imagine="" just="" li="" madness.="" of="" ongoing="" scene="" superman="" surveying="" the="" to="" tutting="" wreckage="">
- "And have a good day!"
- No.
- Ugh, I guess I'll help you if I have to.
- "I'm not that kind of superhero; please stop asking me to fly."
- eh, maybe tomorrow --> -->
Mathy (and I'm not sure what the accompanying costume or scenario is):
- min flow
- P = NP
- "If a vertex cover is polynomial time reducible to..."
- I am a CS major
Onomatopoeia:
- Give me the meatloaf, pow!
- beep boop
- meep
- swagsauce swagu
- Bananana
- pow
- Gotcha!
Entertaining:
- "CATCHPHRASE!!"
- Student X wrote: "ITS helpdesk, this is X how can I help you"
- "I'mma let you finish... but Beyoncé had one of the best music videos of all time!"
The winner was a repeat-offender-for-sarcasm, whose catchphrase, "a pun so infuriating it distracts my enemies," leaves a lot to the imagination while still conveying the right smug tone for a catchphrase. And not really committing to heroism or villainy. (Although some might argue that the entire punnish approach puts it squarely in "villainy".)
