Hey, it's that "spitter" dinosaur from Jurassic Park!

We got to do this in highschool with a straw on some small animals lungs.

A guy I knew at the time goes, "Hey, I got an idea." Pulls out his baloney sandwich and takes a piece out, chews it up and asks if we can try the lungs.

Teacher says sure.

Part way through blowing it up he puts on an excellent act of choking then spits out the baloney, everyone freaks.
