What to Watch Sunday: Three Finales, Fresh Hell, a Shark Attack, an Animal Practice Run and More

On TV this Sunday: The Olympics torch gets snuffed, Longmire and The Glades gun for their season finales, Hell on Wheels gets rolling again, comics do to Roseanne what she once did to the national anthem and NBC monkeys around with a new comedy. As but a supplement to TVLine’s original features (all linked within) here are 11 programs to keep on your radar tonight.

8 pm 2012 Summer Olympics Closing Ceremony (NBC) | And just like that, the flag is passed to Rio de Janeiro. After the London games come to a close, stick around for a sneak preview of Animal Practice, the Peacock’s new sitcom starring Justin Kirk (Weeds) as an anti-social veterinarian, Joanna Garcia Swisher (Better With You) as an ex who re-enters his life and Crystal the monkey (Community) as Dr. Rizzo – ’nuff said. (Animal Practice is scheduled to begin at 10:30, but you know how these things go; you might want to give your DVR a little leeway to make sure you grab the whole episode.)

10 pm Roast of Roseanne (Comedy Central) | Ellen Barkin, Wayne Brady, Gilbert Gottfried, Carrie Fisher, Seth Green, Katey Sagal and at least one surprise blast from the guest of dishonor’s past are among those who’ll take shots at the self-described “domestic goddess.” Glee’s Jane Lynch hosts.

10 pm Weeds (Showtime) | From the network: “Nancy scores big on the first day of her new job.” Somehow, I don’t think they’re talking about getting a great parking space or an office with a window.
