Humility and integrity are major themes. Although much of the movie involves deception and pretending to be someone you're not to impress someone else, ultimately characters learn that they're much happier when they're true to themselves and one another. Honesty and self-acceptance are the foundations of lasting love.
C.D. uses a tennis racket and his feet to hit and batter two drunk jerks who insult him. He also punches a rude man in a bar and manhandles others who are rude to him.
Frequent innuendo and suggestive language, including in relation to C.D.'s large nose ("finally, a man who can satisfy two women at once"). Roxanne runs around naked after being locked out of her house; no sensitive body parts are seen, but there are glimpses of her bottom. References to oral sex. Characters talk about sex ("I mistook sex for love") and reference things such as Playboy magazine in come-on lines.
Fairly frequent language includes several uses of "s--t," plus "p---y" (once), "bastard," "ass," "hell," "a--hole," "d--k," "horny," "knockers," "goddamn," and more.
References to Playboy magazine.
Adults drink wine and beer in bars and restaurants; reference to cocaine in the scene in which C.D. comes up with alternative insults to "big nose." C.D. drinks a slug of alcohol at one point to gird himself for a medical procedure (which doesn't end up happening). Two obviously drunk men insult C.D.
