National Geographic's "Big Cat Week" kicks off with "Snow Leopard of Afghanistan" (7 p.m., Nat Geo Wild), a desperate scavenger hunt for one of the rarest animals on Earth. Getting one to emerge takes more than just putting out a bowl of milk.


Howie Mandel's got a whole new deal. "Take It All" (8 p.m., KARE, Ch. 11), a game show that will air during this time slot every night through Friday, is a little too complex to explain here, but it appears to involve a lot of swapping boxes, deceiving other contestants and fist bumping.


The motorcycle builders competing in "Chopper Live: The Revenge" (8 p.m., Discovery) will have some inspiring background music as the special welcomes Lynyrd Skynyrd, which will perform a new song and "Sweet Home Alabama." Look for contestant Jesse James to get a bit sheepish when the band utters the immortal line: "Does your conscience bother you?"


The New Jersey giants of music -- Jon Bon Jovi and Bruce Springsteen -- join forces to help raise money for those affected by superstorm Sandy in an all-star concert being titled "12-12-12" (6:30 p.m., various channels). Eddie Vedder, Eric Clapton, the Who and Paul McCartney also lend a hand. Where the ladies at?


The stars of "Impractical Jokers" (9 p.m., TruTV) still haven't grown up. For the second season of this juvenile show, the four friends continue to dare one another to annoy everyone from motorists trying to get fast food to people trying to get to appointments from a waiting room. Someone serve these guys a round of knuckle sandwiches.
