OP here. I had cooked a dinner in a sort of celebration of our first night living together, and he offered to do the dishes afterwards. I happily agreed and asked him to leave the skillet for me because it requires extra TLC. When I woke up and found it this morning, I went to work making sure there wasn't too much damage done, and he was horrified when realized what he did. I couldn't be mad at him, because he was only trying to help. Also, for those wondering about why I've kept a skillet for this long. I'm only 23, but it was my grandmothers and then my dad inherited it when she passed away. He passed it on to me when I went to college and got my own apartment. Cast iron, if maintained and loved properly, can be the best tool of a good kitchen and can last forever. It's really not strange to small town southerners to have cast iron pans that are older than them:P

Hey guys, OP here, thanks for the comments! I know I deserve it, drunk me is an idiot, and I think that's the last time I'm going to get drunk for a while... until drunk me knows that my roommate's left! As for other traps, I also found out this morning that I had put some salt in the sugar (which was discovered after taking a sip of coffee), and vaseline or something like that on the bathroom doorknob. Hopefully those are it, but I have a feeling that there's going to be more. My roommate moved out because he's moved to Ireland to be closer to his family, as he's been in England for about a year and a half but prefers Ireland. While he was here, we used to play pranks on each other a lot, but usually practical jokes like whoopee cushions or fake spiders in the other's bed. To be honest, it's a shame I didn't do this prank while he was still here! Thanks for all those who commented/voted on it. No feeling like knowing your fails are public ;D

OP here. Thank you all for your comments and stories. They definitely made my day. I am in the psychology field. When I first started in the field, parents were more apt to work WITH their children and change behaviors in the home. It was not something that took 14 years to realize as much as it's amazing how in just 14 years the parents have changed into the "fix my child" and don't want to work on their part of the issues. Not all parents; I still have a few good ones in the group, but that day was back to back parents. Thank you all again.

OP here. I know that screenshots aren't very good evidence, but it was basically all I had (since the website had been updated since). I'm on a quarter system so there's not enough time to go with a lot of your ideas, though I appreciate you guys trying. Oh, and I did go to my parents. Not for help, since I did everything possible before I called them about it, but they didn't believe me either. （´・ω・｀） Shit just sucks sometimes.
