The South Park Market Research Laboratories is a building that made its only appearance in the Season Three episode "Chinpokomon".
Background[]
In an attempt to have the boys' obsession with the Chinpokomon fad taken away and focused on a new fad, their parents and Mayor McDaniels send them to the South Park Market Research Laboratories building, where they are shown advertisements for other toys. The attempt fails, as The Boys remark the other toys as being "gay".
