Today is Valentine’s Day. With that in mind, here are the romantic backstories of how five pairs of TV lovebirds first met.

•Marge and Homer Simpson: Both attended Springfield High School and met in detention. Marge got in hot water because she had burned her bra (well, it was the ’70s), while Homer got nailed for smoking in the boys’ room.

•Lucy and Ricky Ricardo: In one “I Love Lucy” episode, it was revealed they met on a blind date. But on an episode of “The Lucy-Desi Comedy Hour,” Lucy explained she met Ricky while vacationing in Cuba in 1940.

•Cameron Tucker and Mitchell Pritchett (“Modern Family”): They met at a game night run by their friend Pepper (Nathan Lane), who had briefly dated Cam.

•Wilma and Fred Flintstone, Betty and Barney Rubble: Wilma and Betty worked as cigarette girls/waitresses at a resort where they met and fell in love with their future husbands (who were working there as bellhops).

•Peg and Al Bundy (“Married ... With Children”): Like Marge and Homer, they met in high school. Future shoe salesman Al was the star of the football team.

“Westminster Kennel Club Dog Show” (8 p.m., USA): Release the hounds! We expect some off-the-leash action at the 135th edition of the Westminster Kennel Club Dog Show, where six newly recognized breeds join the fray. The show concludes Tuesday.

“Scrubs” (8:30 P.M., CBS): Sarah Chalke, who won our hearts on “Scrubs,” returns to prime time in “Mad Love.” It’s a new sitcom about four pals in New York and their romantic buffoonery.

DVD RELEASES

Movies available Tuesday on DVD and through digital providers include:

“Unstoppable” (PG-13): Two men must stop an unmanned freight train loaded with combustible liquids. With Denzel Washington, Rosario Dawson and Chris Pine.

“Waiting for ‘Superman’” (PG): Documentary by Davis Guggenheim explores how the American public education system is failing our children, and offers hope for the future.
