cheap ways for math people to have fun...

(1) (a la this afternoon) -- read student reviews of my teaching from the past semester.

(2) (a la last night) -- invite your 30 summer REU students out to dinner, and then over to your house for board games until midnight

(3) (a la tonight) -- go to "plays in the park" and see "the scarlet pimpernel" for $5 with one of your roommates, reading math books for the two hours ahead of time so as to have a good seat

(4) (a la last weekend) -- go over to scott and eric's house, and while playing pool with eric, edit scott's math in clever ways: how many crazy nonsense edits can you catch?
