Sm mf wouldn't let me into the toilet at my school

Title says it all. I had to shit really badly, but some selfish person was hogging the ONLY STALL with a toilet in it. I was considering climbing on top of the wall and dropping one down in on them, but the wall was too tall and smooth. So then I tried pulling the door off, but it wouldn't budge. I finally decided to take a shit in the urinal, because, what else are you supposed to do? I had a lot of beans last night, so I could tell the guy was judging me, but if he cared so much, he could have let me in to shit with him. AIO?
