Why do some people say, "The fact they're spoofing Indiana Jones proves they're fans!" Can you actually quote Matt and Trey saying they are?
South Park simply spoofs what's current. Just like Saturday Night Live simply spoofs anything(mostly in politics) that's current. Outside of those two episodes(which were made when Indiana Jones was in "mainstream news"), I'm unaware of any time South Park has spoofed Indy. Just because they've bothered to spoof Indy in their main story-line doesn't make them fans. By that account, Trey and Matt are "big fans" of
Passion of the Christ and Tom Cruise. They probably just looked at anything news-worthy event and any big occurrence that happened in the past year and said, "Hey, Indiana Jones was big in the news, and it'll be a piece of cake to make fun of Indy, lets combine that with the Olympics and we've got a show!" They could've just said the same for that Raiders Special Edition episode, "Hey, there's rumor of Special Editions of Indiana Jones, lets make fun of anything "special edition" and recreate the end of that first Indiana Jones movie(what's it called again?) when they explode and replace it with Lucas and Spielberg." I'm 100% sure they didn't do it of a labor of love. If it was, they would make fun of Indy on a regular basis.
If they were truly huge Indy fans, I would've expected something smarter as a spoof. Then again, I don't believe either Trey or Matt are actually smart, but that's another story.
