Interesting things to do around campus

So you're bored again. Having exhausted/ignored the suggestions in the last issue of mathNEWS, you want more suggestions on how to spend your time. Well here it is, the second installment of Interesting things to do around campus

• Drop a superball down the staircase in DPL from the 10th floor. If anyone questions you, claim you're doing a physics experiment.
• Read a mathNEWS issue from 2007. There's a stock of them outside the Math Coffee and Donut shop. (Thou shalt not attempt to use thy WatCard!)
• Go fishing in the pond outside the SLC. Bonus points for spearfishing.
• Post XKCD comics in arts buildings.
• Put things into those circular holes on the edges of the floors in DC, then sort them by various characteristics. Bonus points if you can get someone to guess at which sort algorithm you're using. Negative points if it's bogo sort.
• Play the floor tiles in RCH. There's a section of floor tiles outside room 306 that sounds slightly different than the surrounding ones. (I'm not making a map of where the floor tiles sound different everywhere on campus, honestly!)
• Build a tree fort, or get an engineering student to build one for you. Bonus points if it has running water, electricity, and wireless internet.
• Walk into a random exam and write it.

Crap, exams! I totally forgot! Got to run!
