It was about a couple years ago... I had a spicy chicken sandwich from Dairy Queen (and I hadn't eaten there in years, like since the early 80's). Anyway, I'm at home lying in bed, getting ready to sleep, (or was I getting up?). I thought it was gas, the next thing I knew I was like; "Nooo!" Good thing I was just a few feet from my bathroom, and was wearing some old sweat pants over my underwear.
I know it was the sandwich because it was either the grease from it or the mayo was a bit bad. I dunno. It wasn't solid when it came out.
eta: It was this sandwich here.
If flames were to shoot out of your mouth (and it's not even that spicy anyway ), and later s*** will pour out your a**.
