Why does Al Gore say cereal in South Park?

In the episode “Time to Get Cereal” of the American animated television series South Park, Al Gore is enlisted by the main characters in a crisis that is causing the deaths of numerous citizens of South Park.

During the episode, Gore repeatedly says that no one believes him even though he’s being “super cereal” (serious). The phrase “super cereal” is a joke alluding to an apparent cereal/serial pun Gore once made.
