While looking around at Friday the 13th stuff earlier, I ran across this: Friday the 13th Part III with dubbed-over laugh track from a Beverly Hills Episode. It's sort of funny how the laughter immediately transforms the film into a run-of-the-mill sitcom, but the I think the bigger point to take away from this the flipside: that it turns out every bad sitcom has basically been Friday the 13th Part III without the murder.
Someone should add gruesome stabbings to some Friends episodes and start a new horror franchise.
(Sorry if this is too OLD for you, as I see it's existed on the YouTube for a while. It was either this or something about Anne Hathaway in another wedding-related comedy, and this seemed more entertaining.)
