"South Park" co-creators Trey Parker and Matt Stone have been getting the same question over and over on the eve of the premiere of the show's 20th season: When are they going to do a "Pokemon Go" episode?
Their answer? They already did ... 17 years ago.
Parker and Stone on Friday at Comic-Con said their season 11 episode "Chinpokomon," in which a seemingly harmless fad is actually a recruitment strategy for the Japanese army, is basically a "Pokemon Go" episode already.
Stone laughed that the app-based phenomenon "ripped off" their thing.
"South Park" has a big presence at the annual fan convention with an art exhibit and a massive mock-up of the cut-out town outside the convention center.
Season 20 starts airing on Comedy Central on Sept. 14.
