Ari is going to be pulling stunts all week, from stealing clothes and towels while people are in the shower to gluing things to desktops, to making Gay Porn, Little Girl Pictures [and various other offensive material] folders on peoples' desktops then making a screenshot and replacing the desktop image with one that has an undeleteable folder on it. Anything annoying you can think of, he'll do. The crux of it will be when the A, B and G first floor bathrooms (and the C, D and E second floor bathrooms) are completely flooded by Friday morning.
