35. He is claustrophobic
Jason was a kid I knew in my early grades (around K-4th). Jason was Cartman almost literally years before South Park existed. He was an angry fat kid who had been spoiled by clueless single mother. Jason always did things to get attention. One time, we took a trip with our class to an 18th-century fortress.
He decided to put his head into one of the large cannons in front, and his head got stuck.
You can imagine that he was in a claustrophobia-induced rage for the entire time it took to get him out.
