Many sexual gags revolve around Pigeon. Though he appears to be a regular pigeon with no genitalia, it is implied that he has a penis through dialogue and a non-graphic and brief depiction of masturbation.

Crude sexual humor and content throughout.

Bloody violence in many episodes.

"Fuck" is used to the point the series could pass off as a TV-MA series, but as they're all bleeped it remains as TV-14. Unlike most modern Adult Swim shows, the show remains bleeped even on streaming prints, but the DVDs are 100% uncensored.

Pigeon swears the most out of everyone in the series. Every other word he says is vulgar.

Very occasional uses of "Cunt". The word is bleeped out as well in the show while the DVD once again has the word uncensored.

Constant references to Pot Heroin and Cigarettes as well as Semi-graphic use of cocaine
