Duckman is a womanizer (although his attempts often fail). He commonly uses "inventive" references to sex and masturbation.

Duckman and Beatrice are well know for being perverts.

Some comedic violence (explosions, etc.), but characters often don't stay dead.

Duckman kills his stuffed animal assistants nearly every episode, although they never "die."

Duckman's catchphrase is "What the hell are you staring at?!"

Bleeps occur, but not often.

Hell, damn, ass, and occasionally bleeps

Duckman is well known for drinking and smoking

While most of the series is comedic, there are a few points where heavy subjects are handled (Duckman being a widower and feeling unloved are prime examples).
