Margaret has posted a math TA drinking game (her permalinks aren't working, so just scroll down the page) to which I'd like to add a few points.

• Student doesn't staple his/her homework: Gulp and write a snide comment about the locations of various staplers on campus. Take an extra sip if you know more than ten.
  
• Student invents a notation involving more than two subscripts or superscripts: Sip. Dude, you have to be sober enough to finish grading, more or less.
  
• Student emails you franctically, saying s/he overslept and missed class and couldn't turn in his/her homework: Gulp bitterly, remembering all those times you dragged your ass out of bed to your 9:30 am first year physics course to turn in the goddamn problem sets. And accept the homework late, natch.
  
• Student turns in homework reeking of pot: Chug. Hey, if your students are having fun, so should you be!
  
• Student proves something by bad handwriting. Sip. Then write an undecipherable score next to it.
  
  I'm sure there are more ways to make this the weirdest drinking game ever. Discuss among yourselves.
