I once drank a can of soda in which my idiot brother had been putting out his cigarettes.
I am so sorry.
Lets see. So one time when I was in school, my friends and I went into a classroom after school, and sometimes we drew dumb stuff on the white boards with erasable pens. Except this time it wasn't erasable. It was a permanent marker. It took a lot of soap and hard scrubbing to get it off. No one came in and saw our mistake before we got it mostly off.
