Haha, bad roommates are the worst. I roomed with a girl while inpatient once who was an absolute holy terror. She refused to switch to another room too, so I too matters into my own hands and snatched her paperback out of her hands and ripped out a bunch of pages and threw them around like confetti. She flew into a rage and demanded that I pay to replace it, and then stormed out and told the nurse she needed to switch rooms immediately.
I amicably wrote the check while I was signing my discharge paperwork a few weeks later. I would've bought her a Lamborghini if that's what it took to get rid of her.
Here's to financial security and a peaceful household.
