After a satisfying stint in Miami, the "GTL"-loving crew are heading back to where they belong — Seaside Heights, N.J. — when the new season of the reality hit kicks off tonight. Thankfully, the twice ousted and always annoying Angelina is staying in Staten Island this time around, with Snooki's provocative pal, Deena, taking her place in the house. Even with Angelina out of the picture, it doesn't take long for old tensions to resurface, and on their first night out, it becomes clear that some Miami grudges haven't gone anywhere. — Karen Kelty

For all you sadists out there who have had to get your schadenfreude fix watching Wile E. Coyote getting bonked by an anvil while waiting for Wipeout to come back, your wait is over! And not only will the show's hapless contestants be wet and humiliated following their runs on its devilish obstacle course, they'll be cold, too! Season 4 is a winter version, with contestants trying to negotiate such contraptions as a spinning ski lift and a snowplow sweeper. So let the nonsense begin (and let the snowballs fly). — Paul Droesch

Back from their holiday break, the hot docs are greeted with...another shooter. This one isn't in the hospital, but at a nearby college, and the wounds to the docs this time (as opposed to those they must treat) are only psychological. But still. And if you saw Callie shut the door on Arizona as she returned from Africa at the end of the last episode, you know that Callie's psychological wounds haven't healed yet.  Meanwhile, Teddy has a cause — and maybe a new husband. Will cancer patient Henry (Scott Foley) take her up on her offer to marry her for her insurance? — Paul Droesch

As much a part of Cincinnati as Pete Rose and chili on pasta is the annual Crosstown Shootout between Xavier (8-4) and Cincinnati (14-0), which has been won by the upstart Musketeers for the last three years and 11 of the last 15. Judging by their eye-popping 14-0 start, coach Mick Cronin's Bearcats may be primed to finally take down "X" and further demonstrate the scary depth of the Big East. Cashmere Wright and Dion Dixon are smooth guards for defense-oriented Cincy, while Xavier junior Tu Holloway (formerly Terrell) looks to show off a high-scoring game to back up his new name. — Roger Leister
