In this 1990 SliceOfLife RomanticComedy, Vincent "Vinnie" Antonelli (played by SteveMartin) is a wise-cracking, flashy ex-mobster who has entered the Federal Witness Protection Program and is adjusting to suburbia with the help of Barney Coopersmith (played by RickMoranis), an FBI agent assigned to protect him, whose wife just left him for her own selfish reasons.
When Vinnie gets into trouble for committing some local crime, he gets arrested by policewoman Hannah Stubbs (played by JoanCusack), who is not at all happy that someone like him is being under the watch of Barney and vents at the FBI agent when they first meet. The reason for all of Hannah's frustration is because she's a divorced mom stuck raising her two sons.
But as the movie progresses, [[CharacterDevelopment Vinnie learns to shape up]], and [[AwLookTheyReallyDoLoveEachOther Barney and Hannah realize their feelings for each other.]]
!!This movie provides examples of:
* BadLiar: Vinnie is a consummate liar, but sometimes he paints himself in a corner. "Why do you need 25 copies of it?" "In case I want to read it more than once!"
* BelligerentSexualTension: Shown between Barney and Hannah when they first meet.
* BilingualBonus: Vinnie's (probably fictional) dog is named "[[GettingCrapPastTheRadar Fongool]]."
** Hannah's reaction to this indicates she not only understood it, but provides context for the audience that this was Not A Nice Thing To Name A Dog.
* CharacterDevelopment: Vinnie becomes more responsible and it's implied he really does come to love and care about the town. Barney loosens up and learns to enjoy his life.
* ComedicUnderwearExposure: Happens to Barney when Vinnie rebels yet again while they stay at a New York hotel.
* DisgustingPublicToilet: Vinnie doesn't like to use public toilets as shown in two scenes.
* DistractedByTheSexy: Vinnie in the grocery store when he sees Chaldean.
* EmbarrassingNickname: While undercover as someone from Vancouver, Barney is unfortunate enough to get the nickname of "Dicky", much to his dismay.
-->'''Barney:''' Call me "Dicky" one more time, and I'll kill you.
* EvenEvilHasStandards: Vinnie's given reason for why he's testifying. He claims he's actually getting a pretty crappy deal out of the whole thing but he has to do what's right. Whether this is how he actually feels (and felt originally) or if it's just him laying it on for the jury is probably deliberately ambiguous.
* EveryoneChasingYou: The movie's climax following the escape from the courtroom.
* FakeRealTurn: Vinnie gets bored with life as a suburbanite, so he begins a scam that involves getting donations of loose change to "renovate the little league park." At first he plans on just pocketing the money and getting out of town. By the end of the movie, not only does the local little league team have a new place to play, Vinnie is coaching them.
* KarmaHoudini: Vinnie is a criminal who has no real remorse and continues to commit crimes on a daily basis... and is voted the Man of the Year.
* LightBulbJoke[=/=]SoUnfunnyItsFunny: "What's the difference between a light bulb and a pregnant woman? You can unscrew a light bulb."
* RunningGag: Barney never seems to remember to unfasten his seat belt before trying to get out of the car.
** On the 3rd and final time, he becomes aware of this habit.
* StraightManAndWiseGuy: Barney and Vinnie
* SuperOCD: Barney is implied to have this when he eats pancakes.
** Really, about everything he does.
