Prolly cuz it was "original" as I explained, rather than bought from some other region who had already had the idea of a comedy dub. Here it was insanely famous when it aired, though. People of all ages know the show. Like, almost anyone anywhere in the country would recognize it. In case you are curious (no idea if you speak Spanish), it's called Humor Amarillo (basically, Yellow Humor. Yes, it's a racist title that even makes fun of the comedy dub itself) and can be found in YouTube, I believe.
