Character mistake: Ben Stein asks a chemistry question about -273° Kelvin. The problem is, the scientific community never uses the word 'degrees' when referring to Kelvin. The correct way to say it would have been, "-273 Kelvin is also known as what?" Also Kelvin cannot be negative since 0 kelvin (approx -273° Celsius) is absolute zero.

Trivia: One of the show's creators made a cartoon about a retarded pig. Boomhauer's voice is based on the voice of an angry viewer who called when he was offended by the cartoon.
