At first glance, this version of Mariah Carey’s “Touch My Body” video (the one with Jack McBrayer as the nerd) in which everything but Mariah (including her hands) is replaced by a green screen looks like an invitation by the artist creator to insert your own footage, but I think Rich Four Four is right about it being an art project on its own and not raw material for a basement creation:

It would be interesting to see someone try to make their own video out of it, long-sections-of-time-and-space-without-Mariah and all, though. There has to be someone out there on YouTube with that kind of time.
