In an effort to dissuade the boys from the anti-American influence of the Japanese franchise Chinpokomon, the parents try marketing research on new toys. The boys are taken to a room and shown various commercials, including one for the Wild Wacky Action Bike.
The bike is shown to require the rider to steer the front and rear wheels simultaneously, making it almost impossible to steer in the right direction. It also sports two more wheels, one that is oblong and makes the bike prone to being slow and rocky while in use while the smaller of the two merely keeps it balanced. It also glows in the dark.
In the commercial, the boy riding the bike quickly loses control of it and slams into the rear of a large semi, possibly killing him. The boys watching the commercial quickly write off the highly defective bike as being "gay" and refuse it altogether.
- "Chinpokomon" - Seen being shown to the boys in a focus group as an alternative to Chinpokomon.
