We just can't get enough of Will Arnett.
Wild Russia (5 p.m., ANIMAL): Siberia covers almost ten percent of the Earth's surface. (Who knew?) Spend an hour exploring this mysterious, ice-covered region -- without donning a coat or leaving the couch -- in this new episode of Wild Russia.
30 Rock (8 p.m., NBC): With 22 Emmy noms, 30 Rock is sitting on top of the world. But just three short years ago it was an infant sitcom, wobbly on its feet and unsure in its words. In this this gem from Season 1, Will Arnett guest stars as Devon Banks a business rival of Jack Donaghy's (Alec Baldwin) who is hot for Kenneth the Page (Jack McBrayer).
The Smoking Gun Presents: World's Dumbest Criminals (9 p.m., truTV): It seems like the world's supply of idiots is endless. The Smoking Gun ran yet another edition of "World's Dumbest Criminals" last week (they're up to 14!) and it's re-airing tonight in case you missed your dose of foolish felons.
Ace of Cakes (10 p.m., FOOD): The wizards at Charm City Cakes in Baltimore, Maryland are about to work their magic on one seriously daunting dessert: a Cirque du Soleil-themed cake. We're expecting an elaborate confectionery contraption, complete with tightropes, acrobats, and a mini light show.
The Real Housewives of Atlanta (10 p.m., BRAVO): Here comes another in-depth look at a catty cross-section of home life. BRAVO's lavish "Real Housewives" franchise is heading south to Atlanta -- meet Kandi, Sheree, NeNe, Kim, and Lisa in tonight's season premiere.
