The crazy cop duo is a staple of modern cinema. For some reason, audiences flock to movies about two mismatched police officers almost as enthusiastically as to movies about real and/or animated penguins. If you're a crazy cop pairing fan, you'll love these seven. Enjoy - and one more screw-up like this and you're off the case!

Jack Cates and Reggie Hammond, 48 Hrs.

It all began here. And by "it" I mean "the buddy cop genre," not "Nick Nolte's gradual slide into insanity." The basic premise here is that grizzled police detective Cates (Nick Nolte) has to team up with wisecracking small-time criminal Hammond (Eddie Murphy) to catch The Bad Guy. The crazy part of this duo comes from the fact that not only is Nick Nolte a really obvious racist, but he seems to hate most white people too. The perpetually apoplectic Nolte and the laid-back wise-ass Murphy are a match made in crazy cop heaven, if such a place exists.

Joe Friday and Pep Streebek, Dragnet

Dan Aykroyd is the fast-talking by-the-books police officer Joe Friday. Tom Hanks is the hilariously-named Pep Streebek, one of these new kind of cops who doesn't keep his car clean. Together they fight over things like hair, wardrobe, and chilli dogs. But eventually they end up forming a friendship, and taking down the evil Christopher Plummer in the process. Hooray for crazy cop duos who eventually learn to respect each other and save the day!

James Carter and Lee, Rush Hour

One cool way to insert a little craziness into a police duo is to introduce a major language barrier. That's the general idea behind Rush Hour and its sequels, which pairs motormouthed Chris Tucker with Chinese fella Jackie Chan, who's really good at karate but not so good at communicating with Chris Tucker. They get into all kinds of action-comedy hijinks, but they eventually save the day at the end. At least until Rush Hour 4: Jackie Chan Kills Chris Tucker is finally released.

Allen Gamble and Terry Hoitz, The Other Guys

Even by crazy cop standards, these two are a little nuts. Gamble is Will Ferrell, a forensic accountant (yes, they apparently exist) who's never fired his gun. Hoitz is Mark Wahlberg, a hothead who's been stuck in the accounting department ever since he accidentally shot Derek Jeter at the World Series. They're thrust into the spotlight after a couple hotshot cops inexplicably jump off of a tall building, and it only gets crazier from there. One memorable example is their employment of the "bad cop, worse cop" routine, in which Wahlberg acts really intimidating towards the subject and Will Ferrell acts even worse, going bonkers and throwing furniture around. It does not work.

Jake Riley and the Replicant, Replicant

Possibly the most insane law enforcement duo in the history movies, and you might not have ever heard of it because it's a direct-to-video movie starring Michael Rooker and Jean-Claude Van Damme. But don't go by its reputation - Rooker plays a recently-retired police detective who is tormented by the serial killer he was never able to catch (Jean-Claude Van Damme). So he's contacted by a top-secret government agency who has a crazy plan to end all crazy plans: They made a clone of the murderer (JCVD again, with the mind of a very young child) who has a psychic connection with him. And the clone has to live in Rooker's house until they catch the guy. I am not making this up. The craziest scene is probably the childlike JCVD's encounter with a prostitute, but you should really just watch the movie for yourself.

Ivan Danko and Art Ridžic, Red Heat

Another buddy cop genre entry from 48 Hrs.' Walter Hill, Red Heat pairs a Russian detective played by Arnold Schwarzenegger with a Chicago cop played by Jim Belushi. These two acting powerhouses proceed to get on each other's nerves after a series of plot developments force them together in order to track down a villainous crime lord.  Schwarzenegger fans know he can bring the crazy (in a good way!) and Belushi is no slouch in this department.

Nicholas Angel and Danny Butterman, Hot Fuzz

An underused comedy trope is the guy who's really, really good at his job. It gets a workout in Hot Fuzz, the genre-spoofing modern classic from Edgar Wright. Nicholas Angel is that guy, and he's partnered with the less-underused trope of a dumb fat guy who's terrible at his job and has a funny name to boot (Butterman. Ha.). They make it work somehow, though, and in between messy ice cream bars they take down the bad guy, just like it's supposed to happen. Crazy!
