''Leonard Part 6'' is a 1987 big-screen comedy for Creator/BillCosby -- and [[http://www.agonybooth.com/recaps/Leonard_Part_6_1987.aspx so notoriously bad]] that the star himself [[CreatorBacklash told people not to see it]]. Cosby was contractually obligated to promote the movie. They didn't specify '''[[LoopholeAbuse how]]''' he could promote the movie. Cosby appeared on every late night talk show warning people to stay away.

The story is ostensibly the sixth great adventure of top CIA agent Leonard Parker (Cosby), the others remaining classified for now. Leonard has gained a wide variety of eccentric skills over the years, and now that he's been brought out of retirement to stop a plot by evil vegetarians who plan to train animals to kill people, he'll have to use most all of them to save the day... and his relationships with his ex-wife and daughter, while he's at it.

* AbortedArc: The MayDecemberRomance between Joan and Giorgio never gets resolved.
* AnimalAssassin: The evil vegetarians plan to train animals to kill people.
* AnimatedCreditsOpening: The credits are accompanied by crude animations out of animal drawings.
* AwardBaitSong: "Without You", performed by Peabo Bryson (a few years before he became one of the go-to guys for this trope) and Regina Belle. It was actually a radio hit.
* BodyDouble: Fairly obvious when Leonard has to dance. The reason for the weird helmet was to ensure no one would notice it wasn't Cosby.
* ChekhovsArmory: A psychic gives Leonard an arsenal of DeusExMachina items such as melted butter (to scare killer lobsters.)
* CoolCar: Leonard's armored, camo-colored, tank-turreted Porsche.
* CoversAlwaysLie: That DVD cover as the trope image? Leonard never appears that way. For whatever reason, the distributor was hoping to capitalize on the success of ''Film/TheAdventuresOfPlutoNash''. Let ''that'' sink in. (For the record, ''this'' [[http://www.impawards.com/1987/leonard_part_six_ver2.html is the actual movie poster]].)
* DanceBattler: Leonard's ballet lessons [[NoodleIncident when he was undercover with the Bolshoi ballet]] helps him when he fights Medusa's minions.
* EvilIsHammy / LargeHam: Medusa is entertainingly over-the-top.
* EvilVegetarian: Medusa.
* FoodSlap: Leonard ends up wearing most of the meal when he dines with his estranged wife - both times.
* FruitOfTheLoon: The film made a point of depicting the vegetarian villain look extra-crazy by having her always eating fruit while she ordered around her mooks and pursuing her wacky plans. Mind you, this is a food-obsessed movie anyway.
-->'''Medusa:''' Grape me!!
* KitchenChase: Monroe is shooting at Leonard with a revolver, switches to an uzi, then switches to another revolver, and his shooting "accidentally" opens a bag of coffee beans into a coffee grinder, breaks a couple eggs for frying, and punctures a carton of oil which some eager chefs help themselves to for cooking.
* OffscreenMomentOfAwesome: Invoked InUniverse during the intro by Leonard's butler, who said Parts 1 through 5 were so awesome they had to be classified. [[InformedAbility Take their word for it.]]
* ProductPlacement: One scene contains a refrigerator full of Coca-Cola cans (Creator/ColumbiaPictures' owner at the time), whose labels are all conveniently facing the camera. Elsewhere, a table with a huge stack of Lava Soap bars upon it appears backstage at a theater, and Alka-Seltzer proves vital to the climax. Creator/RogerEbert went into a rant about this while reviewing the film on ''Series/SiskelAndEbert''; see BerserkButton on the series' page for the full quote.
* RetroactiveLegacy: Supposedly the sixth in a series featuring the eponymous character.
* RoadTripAcrossTheStreet: The "agonizing ride" for Leonard to see his estranged wife.
* SelfSurgery: Played for laughs as Bill Cosby's character removes a bullet from his own shoulder.
* TakeThat: The character of Leonard's daughter is widely seen as an attack on Lisa Bonet and her role in ''Film/AngelHeart'', especially the theater scene in which she removes her clothes for no real reason.
* UnInstallment: We never did see Parts 1 through 5... because they were locked up "in the interests of world security".
* UnusualWeaponMounting
* UnusuallyUninterestingSight: The chefs from Leonard's restaurant don't think much of a hitman attempting to murder their boss....
* WeHaveToGetTheBulletOut: Leonard, having been shot, removes the bullets himself, his trusty manservant only standing by with surgical tools and a mirror. Given the large jar full of bullets that the extracted slug ends up in, this is not the first time he's had to do this by a long shot.
* WeaponizedAnimal: The movie included an ostrich with missile launchers mounted on it.
* WeaponizedCar: Leonrd's spy car has a cannon turret on its hood, which made some geeks wish for a ''TabletopGame/CarWars'' movie instead.
* YourHeadAsplode: This happens to one of Medusa's {{mook}}s in the climax, as the unexpected-by-''anyone'' result of Leonard forcing him to taste meat.
There are no ''Leonard Parts 1 through 5'', if you were wondering. The title itself is a spoof of [[{{Sequelitis}} multi-part spy thrillers]]. And even if there were prequels, Cosby would have probably destroyed them all by now. Or traded them in for a lifetime supply of pudding and JELL-O.
