Bad Lip Reading isn't just for sports

What if the Avengers were actually a bunch of hillbilly's trying to have relations with people they're related to?

I know there must be some sort of science-y thing that explains how to do this. The lip reading is really dead on with character actions. Loki asks Black Widow to get him some chew from the Piggly Wiggly and then spits on the glass. It's as if this were the real movie they meant to release.
