Quite a bit of suggestive material.

Lots of woman with revealing outfits in season 4 and 5.

In Season 5 Episode 12 Will brings Lisa's father to a strip club.

In one episode a large man walks in a room threatening the two protagonists and Will punches him to no effect

some episodes are fairly violent

A violent dream sequence is played, and Carlton, who is a criminal, punches a butler

some comical violence(i.e. will hits carlton for fun)

a gun is used once, a man is shot(offscreen)

In a season 5 episode, 3 girls say "They say Mr. Smith is a bad mother-" before being interrupted.

Will makes short jokes to Carlton quite often.

a few profanities, hell, damn, ass, and bastard.

Carlton says that something is retarded when he is in jail.

Will makes fat jokes to Uncle Phil often.

a few scenes take place in bars. people seen drinking. a few times we see people smoking cigarettes. one episode involves the drug speed.

none really, a few episodes do have sad moments. but these sad moments easily turn into more happy moments because will provides comic relief
