[South Park] Why did the aliens who set up Earth as a reality show allow a poor kid from Africa and Sally Struthers to get their hands on interstellar travel technology?

That just seems like it runs a major risk of allowing themselves to be discovered.

It was a 2 part crossover with the popular sitcom "Everyone marklars marklar". Both shows got a little ratings bump from it, but it was a short term thing.

They tried a similar cross over with "who wants to be a member of the galactic federation " but the earthlings crashed out in the first round and the producers pretty much abandoned all further crossover plans.
