One time I went snowboarding with an ex-girlfriends family.
We were gone all day and got back real late at night. I went to use the bathroom before I went home, since I hadn't gone all day on the mountain.
The "main" bathroom was in use, so I was offered use her parents bedrooms bathroom. I fuckin destroyed it, probably the most shit in one sitting of my whole life, followed by pure evil. Probably 15 minutes of solid work put it in.
Comes time to flush, and nothing goes down, and the water starts coming up. You know that "almost heart attack" feeling when the water rises, reaches the top of the bowl, then relief as it all goes back down? It didn't go back down, the water came up and up, and over flowed my shit into their bedroom bathroom, out the door into their bedroom.
So there I am, cleaning up my shit at 2am while these people are trying to go to bed.
cool story, bro.
