on cold-calling

Wings and Vodka has a brilliant post about class participation strategies.

To his list, I'd like to add The EU:

The EU
(This only works if your prof calls on people by row.)
1) Wear a suit. If you can, get some of your classmates to wear suits as well--it's more convincing that way.
2) Before class, tell your prof you need to leave early for an interview. (note: this compromises anonymity and is thus moderately risky.)
3) Wait until he calls on your neighbor.
4) Leave.
5) Refrain from fist-pumping exultation until safely out in hallway.
