A lot of sex references from Phil but they're always played for laughs
Minor references/innuendos to copulation. Such as "how about a little pat pat" Unlikely that kids would catch it and probably the same for many adults.
Violence & Gore
Mild
some explosions but it is a favorite thing of the family to do
Duck hunting scenes but you only see the guns go off
Some scenes of animals being skinned but it's within the context of the hunting life
Profanity
None
Uses of freakin, and crap throughout the series and in season one their is one censored use of s*it and a*ss and one use of hell.
