If you were trapped in a completely plain room...

[Alxprit]

I'd Wess Dance as hard as I could.

Also, I'd tell my deepest, darkest secrets to the air because I just need to say them out loud.

Then I'd steal the technology that took me from wherever I was and put me in the room. AND USE IT FOR THE GOOD OF SCIENCE

^This.

I'd also sneak in some kind of marker hidden in my jacket pockect and draw stuff on the walls. Or I'd daydream, sleep and eat, start singing random songs really badly and slowly go insane XD

 

[shiny jiggly]

I'd probably check to see if there are any openings, use every one of the tools/random things on hand to try to break out, give up and go back to sleep, scream really loudly to test out the acoustics of the room, try to break dance, and somewhat fail, sit around and do nothing, check to see if there are any surveillance cameras in the corners, show off my (almost non-existant) dance moves, sleep more and wake up to figure out that I'm actually stuck in there, stare at the ceiling, (try to) do yoga, run out of ideas, eventually become crazy, eventually find out that it is some kind of test room that was used to test various things when the universe was being programmed, sit down and think for a while, pee in a corner because I can't hold it in any longer, sleep more, complain about the accommodations, try to develop psychic powers (more like psycho powers)...

Jerk off. Hey, no one's watching.

(Then go to sleep, then eat food and drink water)
