Three new doses of 'reality'

THAT'S THE GREAT thing about TV. Every week - heck, every day - delivers another passel of peculiarity potential. Especially among "unscripted" cable shows.

Tonight's cable lineup includes at least three more, summarized herein to aid your viewing choices or lack of same.

_ "Tickle" (10 p.m., Discovery).

Because "Moonshiners" jus' ain't 'nuff, here's a spin-off, featuring the bleary-eyed drawler of the title. Turns out Tickle has "stumbled" on a hidden stash of 'shine in a ravine. (Cameras in tow, of course.) So he turns his attention from making to marketing.

"Tickle must remain careful," Discovery publicity materials warn, "to dodge the authorities, snooping townspeople and, most importantly, the true owners, who may or may not have serious criminal ties." ("Moonshiners" airs 9 a.m.-1 p.m. today on Discovery.)

_ "Porter Ridge" (10:30 p.m., Discovery).

Thanks to the insatiable appetite for "Duck Dynasty," that hit show's creators now head north to "the rolling hills of Indiana" and shirtless junkyarder Terry Porter and his "backwoods clan." Cue the dialogue subtitles!

Here come scrapper Dirty Andy, blowtorch boy Danny Bob, garbage man Elvis Larry, "country calendar model" Kayla and "a dadgum bear." Expect hair, beards, wrasslers and bears! (BTW, "Duck Dynasty" returns to A&E tomorrow at 10 p.m.)

_ "Doomsday Castle" (10 p.m., NatGeo).

Another spin-off, from survivalist smash "Doomsday Preppers," this debut spotlights "disaster preparedness" in a half-built castle in the Carolina mountains.

You might think disaster prep involves extra water, spare batteries, plywood and duct tape. But, no. Here - with camo-clothed former infantry trainer Brent Bruns and his five adult offspring awaiting the "end of days" from an electromagnetic pulse - it's a "hoarder's paradise" of a bunker, plus surprise attack drills and MREs for dinner. ("Doomsday Preppers" runs on NatGeo today 9 a.m.-noon and 6-10 p.m.; new episodes start tonight at 9.)
