On the east coast, at least, NBC accidentally ran the real closing credits, rather than the network's generic reformatted ones, for the original broadcast.
Kathy Najimy does not appear in this episode.
This spoof of the film "Sliding Doors" was originally scheduled to air on 15 Nov 99, but got bumped last minute in lieu of the return of World's Most Amazing Videos. NBC didn't want Veronica's Closet to have to go up against ABC's Who Wants to Be a Millionaire. (Episode 51 had to go up against it anyway when ABC extended Millionaire's planned run by three extra days.)
