LifetimeMovieThe only thing worse than buying a mail-order bride online is being bilked by teenage girls who had set up the account. So the dude in “The Bride He Bought Online” (Lifetime, 8 p.m.) vows revenge. The Catfishing game gone stars Anne Winters, Travis Hammer, Lauren Gaw and Annalisa Cochrane. Sounds terrible.

Strange tries to drive himself crazy on “Jonathan Strange & Mr. Norrell” (BBC America, 10 p.m.). Which is why they call him Strange.

“Dr. Jeff: Rocky Mountain Vet” (Animal Planet, 10 p.m.) rides around, fixes animals and hums John Denver songs.

I’m not sure you’re aware Jim Belushi (“Life with Jim”) is on one of those celebrity house rehab shows: “Building Belushi” (DIY, 10 and 10:30 p.m.)

Jason’s heart has been blackened on “Atlantis” (BBC America, 9 p.m.) and that’s a hard spot to remove.

A grandmother lives a double life on “Tabloid” (Investigagion Discovery, 10 p.m.), hosted by Jerry Springer.

Turner Classic Films goes on the campaign trail tonight with “The Candidate” (8 p.m.), “The Last Hurrah” (10 p.m.) and “The Dark Horse” (12:15 a.m.). It later turns to horror with “Equinox” 9TCM, 2 a.m.) and “Bloody Birthday” (3:45 a.m.).

“The Maze Runner” (HBO, 8 p.m.) makes its premium cable debut, as does “Ouija” (Cinemax, 10 p.m.).

An animated double feature offers “The Incredibles” (ABC Family, 8 p.m.) and “Toy Story 3” (ABC Family, 10 p.m.).

I have strong affection to the film “Step Brothers” (Comedy Central, 6:30 and 8:45 p.m.).

Baseball includes Seattle at Yankees (MLB, 1 p.m.), Dodgers at Washington (Fox Sports 1, 4 p.m.), Cleveland at Cincinnati (Fox Sports 1, 7 p.m.) and Boston at Angels (MLB, 9 p.m.).

Third round play continues in the British Open (ESPN, 7 a.m.).
