Megan R. and I found ourselves with some time on our hands, and were feeling particularly mischievous, so here's what happened:

We knew that Tadhg, (pronounced Taig, for the record. Irish, huh?), who is one of Brendan's housemates, always locked his door unless he was in the apartment. The other boys left their doors open all the time. We knew from Katt, another one of the housemates, that Tadhg was in the living area watching television, so we sent her in to distract him so we could go into his room without him knowing. We made post-its with labels and put them all over EVERYTHING: "Tadhg's door," "Tadhg's light," "Tadhg's wall," "Tadhg's dirty sock," etc.
We decided that any pieces of clothing on the floor would say "dirty" and any hanging up or in the closet would just say "Tadhg's shirt." We ran around as fast as we could, and in the about five minutes we were able to cover the whole room, and all his possessions, with post-its. His smoke alarm, his mirror, his shoes, his socks, his books, his passport, his toilet, everything.

Here you can see some of the floor labels on clothes, carpet, shoes, and dirty socks.

We rolled one up in his toilet paper so that he wouldn't find it for a little while. haha

After we finished, we went into the kitchen as if we'd never been there, and sat down with Tadhg and Katt and watched television. We couldn't stop laughing, so eventually he got up and left. We followed him from a distance to his room so that we could hear his reaction, and we definitely got our money's worth :)
Although he has peeled most of them off, he stuck them all to one of his walls as a display.

Then we broke into Mickey's room and did the exact same thing, which he found two days later and hasn't removed one post-it yet. We had a bet that it would take him over a day to realize it, because his room is such a boyish disaster, but apparently he noticed immediately and was too lazy to do anything about it. Success :)
