Occasionally there is some mild sexual innuendo (the most direct is probably when Mister Ed is flipping through a Playhorse calendar). But it will definitely fly over kids' heads.

Barely ever, and then only comical.

A few episode someone called another one Jackass.

Infrequent use of "devil". But this is not a show known to have swearing in it.

"Darn" is sometimes used, but this barely counts.

Some episodes contain drinking.
