The floor in my dorm...

[Jonathan Meer]

Put flour in a ziploc bag and stash it away in your RD's room when he isn't there. Then, create an opportune moment to reveal the stash.

Piss into a cookie sheet and lay the sheet in a freezer. Then, when someone leaves for the weekend and locks their door, remove the piss sheet and slide under their door. Alternatively, you could stuff a ziploc bag full of shaving cream, place the lips underneath the door, and stomp on it.

Walk into random people's rooms, and rip the sheets off their bed. With practice, one can remove nearly any sheet with one clean motion. Then, wordlessly, exit the room.

Strip to the gizzard and stand in a circle around the elevator on a particular floor, stark naked. Demand a ten-cent toll before they can enter the elevator, and if they refuse, slowly creep closer to their body.

If there are no windows in the bathroom, shut the lights off on someone either: showering, pissing, or pooping.

Screenlock random people when they're out of their room. Take a screenshot of someone's desktop, right click the desktop and deselect 'Show Desktop Icons', which is under 'Arrange Icons By'. Then, set the desktop background to the screenshot you just took. Effectively, everything looks the exact same as it did before you touched it, except that they cannot click the icons (which are actually just pictures).

Grab a set of portable speakers and a musical device and blast Rick Astley in the halls while jogging around marathon-style.

Piss into a water bottle and put it in a guy's refrigerator.

Remove every item from someone's room and set it back up in the bathroom.

Question: Does the dorm have ceiling tiles, and are they removable?

EDIT: Pretend that you've never heard the figures of speech people throw at you, and ask them to explain them. EXAMPLE: "Of course? What? What's that supposed to mean?"

If you're amazing talented, speak in iambic pentameter.

Hide two food items in a person's room that will go bad, such as an orange or an egg. Place them in an easy-to-find area. When asked about it, admit that you placed them there, then ask if he found the other three. Refuse to tell him where the imaginary items are.
