Webcomic: Nip and Tuck

aka: Nipand Tuck
Nip And Tuck is one of Ralph Hayes, Jr.'s webcomics (Goblin Hollow and Tales of the Questor are among his others).

The main focus is on Nip and Tuck Todd, two fox brothers of the somewhat loopy Malarky County, located somewhere (judging by the cast's accents) in the southern USA. Throughout the series, the brothers get mixed up in various hijinx, including babysitting a pair of rival budding evil geniuses, accidentally entering Tuck's girlfriend into a porno photoshoot, helping a rookie journalist try to prove the existence of the local lake monster to the world, training a junior boxer to fight the town bully, and even MST-ing Nip's movies.

The strip is on indefinite hiatus (though the characters have been transplanted to Goblin Hollow for the time being), but the archives are still available.
