I don't even know what category to put this thing in. TV, Football, Music? I'll go with Random.
A YouTube video has been going around the sports blogs (Deadspin, With Leather) that shows Tony Romo and Mr. Belding from "Saved By The Bell" singing Journey's "Don't Stop Believing" with glam metal tribute band Metal Skool. Oh, and Romo is obviously drunk.
My first instinct was "body double" as well, but then I remembered that Edie Falco did a succesful run of "Frankie and Johnny at the Clair de Lune" on Broadway a few years ago and that show requires some pretty explicit nudity.
