It’s a natural pairing.

Start with the Farrelly brothers, creators of such rude and crude comedies as “Something About Mary” and “Dumb and Dumber.”

Their new sitcom, “Unhitched,” debuts at 9:30 p.m. Sunday on Fox, the network that exemplifies rude TV comedy, starting with “Married … With Children.”

Suffice it to say that “Unhitched” is not a nuanced work. Still, it has its moments.

The sitcom focuses on four friends in their 30s living in Boston, who find themselves back drowning in the dating pool when their former relationships dissolve.

There’s Jack “Gator” Gately (played by Craig Bierko), a charismatic financial analyst who suddenly finds himself single again after his wife leaves him for a circus performer. He’s hesistantly dating again, hoping to find “the one.”

Joining him are his best friends, hounddog Tommy (Johnny Sneed), the thrice-divorced brewmaster at a microbrewery, and Freddy (Shaun Majumber), a talented surgeon who is inept around women.

Offering the female perspective is Kate (Rashida Jones, “The Office”), an attorney who handled the divorces for all three and who lives next door.

“Unhitched” has a sweet quality to it, surprising given its pedigree, and the quartet has a nice sense of camaraderie as its members suffer through some of the freaks on the singles scene.

Still it’s hardly a great fit among Fox’s animated comedies, as it’s not the cartoon that one might expect. Unfortunately, it’s not different enough to stand out and flourish.
