The meth hogs were a group of domesticated pigs owned by Early Cuyler to use in his pig hunting safari after buying real estate. Lil gave them a sample of methamphetamine which made them act strangely.
Meth Hogs
 The pigs are later seen in a spoof of an advisory commerical about drugs.

The commercial read as follows: "Is your hog on drugs? How would you know? How could you tell? Look for these here warnin' signs. Sudden weight loss. Euphoria leadin' to paranoia. Stealitization of your thangs. And jibbery-style oinkery what make no sense a 'tall. Warn your hog about the dangers of meth a 'fore it's too damn late. I'm Early Cuyler and this concludes my court-ordered community service."
