Ah, the good ol’ days of shakes, fries and Le Big Macs.

Anytime you attempt a mashup of two beloved TV shows or films, the results can be messy. Like unfortunate-character-in-a-Quentin-Tarantino film messy. But this time it works out with “Happy Days” and “Pulp Fiction.” One is a violent, bloody trudge through the world of crime and hit men, and the other is “Pulp Fiction.” Heh, we kid, possible deadly assassin Richie Cunningham.

Las Vegas-based video editor Robert Jones brings us this delightful bit of nostalgia, set to the beloved theme song of “Happy Days” and splattered with a lot of Tarantino style a la “Pulp Fiction.”
