Game Show in My Head 8 p.m., Channel 4

Ashton Kutcher's new reality show, which premieres tonight, riffs on "Punk'd," Kutcher's previous adventure in good-natured psychological abuse. The premise is simple: Players are instructed via an earpiece to perform outrageous acts in public for money. Tonight's victims, er, contestants, are a personal trainer from Salt Lake City and a Buffalo entrepreneur.

Underdog to Wonderdog 8 p.m., Animal Planet

The extreme-makeover gravy train rolls into the local animal shelter, where the Doggie Wonder Dream Team - a trainer, groomer, carpenter (we can only assume he's on custom doghouse duty), and host - tap down-on-their-luck pups for Cinderella-caliber transformations. A loving home, natch, is the icing on the dog biscuit. Tonight's lucky canine is Lucky, a skittish Yorkie.
