Kenny (Noah Galvin) gets an assist from out athletes/Instagram thirst traps Robbie Rogers and Gus Kenworthy when he joins the wrestling team. Does Kenny have what it takes to become the champ? (We don't know how wrestling works.) Find out on The Real O'Neals Tuesday at 9:30 p.m. Eastern on ABC.

You can't stop the beat, but you can certainly try when beloved musical Hairspray gets the live televised treatment Wednesday at 8 p.m. Eastern on NBC. This year's holiday special stars Ariana Grande, Jennifer Hudson, Harvey Fierstein, Kristin Chenoweth, Ephraim Sykes and more. It won't pack the same twisted charm as John Waters' original film, but a few years into the television musical craze, they've gotten pretty good about recreating the stage show.

If you like ‘em big and thick and charming, set your DVRs to see WWE superstar John Cena take the hosting reigns on SNL this week, Saturday at 11:30 p.m. Eastern on NBC. The massively popular Cena is on his way to being the next Dwayne “The Rock” Johnson and cross over from WWE to mainstream Hollywood. If it means more mostly-naked scenes like his spot in Trainwreck, we're all for it.
