How to Eat with Your Butt/Trivia

Kenny's Death
After the Thompsons reunite with their son, Kenny and Cartman cross the street when a motorcyclist suddenly runs Kenny over, crushing him. Cartman is amused and Stan and Kyle don't say their usual lines. Earlier in the episode, it was reported that people were getting randomly squashed by motorcycles.

Goofs

 * The Thompsons had claimed that their son's name was "Tommy," but one of the men at the reunion celebration said the boy was called "Billy." Tommy could've been a nickname however.


 * When Ben Affleck is identified as their son, his shirt continually alternates between colors. One minute it's khaki, the next it's white, then it's khaki again.


 * When Cartman has his picture taken, he drops his hat. In the next scene, he takes his hat from his back pocket, not the floor.
 * In the last scene of this episode, Cartman is missing his double chin.
 * The Thompsons stated their son was missing since 1982 which would have been 19 years ago from 2001 (When this episode took place). But it was mentioned to have been 20 years ago.
