IamA Janitor (and I'll actually answer your questions) AMA!
I'm a janitor at one of the biggest party colleges in the country. I've seen some shit. AMA.

EDIT - Quick lesson in vernacular. Janitor is someone whose job is to primarily clean his area. Custodians are responsible for cleaning and maintenance of the area. The more you know!
I gotta go, everyone. Thanks for keeping me company! Please do me a favor, and thank your local janitor. It's a thankless job, and they work really hard. Have a good night!
EDIT 2 - Wow, this blew up. I'll do my best to answer what I can, everyone. Bare (or is it bear) with me.
FINAL EDIT - Okay, I think the thread has lost its muster. If I see any more questions on here I'll answer as best I can, but I'm no longer going to be spamming F5 in anticipation of more questions.
May your porcelain ever sparkle.
