Hybrids set to rule roads of South Park?

Leave it to South Park to pick up on a thread weaving its way through popular culture. This week's episode, "Smug Alert," is summaried thusly:

"Stan persuades all the citizens of South Park to buy hybrid cars."

Leaves much to the imagination, doesn't it? So how is South Park going to spin this one? A tongue-in-cheek, yet moral lesson on the importance of alternative drivetrains to the environment? One thing's for sure, fans are unlikely to see Chef piloting a new Prius lovemobile.

Jot your predictions down in the comments section -- we're eager to hear them.
