Fan Question: I remember hearing somewhere that there’s an alien Visitor hidden in every episode of South Park. Is that true???
Answer: This is probably one of South Park’s greatest myths. And despite what you heard through the alien-probe grapevine, the answer is actually no.
Although Visitors do appear in SOME episodes, they definitely are not hidden in every single episode. But that doesn’t mean they don’t pop up randomly — like driving limos in “Cow Days”, or going drag in the crowd of a beauty pageant (in “Dead Celebrities”).
As for WHY the aliens are there — we learned in “Cancelled” that the Visitors work for a universal TV company called Nerzod Productions, and they are there to help fix the thousands of satellite dishes hidden in Earthling’s rectums.
