This reminds me.
When I moved into my apartment this year, my roommates arrived a few days earlier than I had. It's a four bedroom, two bathroom apartment. One bathroom for each pair of rooms.
Apparently on day one, when they didn't have any supplies or toiletries, one of them took a shit before realizing there was no toilet paper, and cleaned it off in the shower. The problem is that this was my bathroom and not his.
Thanks for reminding me, I have to beat the crap out of him next time I see him. Or take a shit in his shower.
