Romance seems to be all over the place on TV tonight. I wonder why?
"Unsolved Mysteries" (8 p.m.-9 p.m., WBAL, Channel 11) -- "UM" wishes everyone a Happy Valentine's Day by looking at a bunch of alleged aphrodisiacs, seeking answers to the burning question of whether such foods as chocolate, honey and oysters can affect one's sex drive. Plus, is it really possible that an asteroid could crash into the Earth, ending life as we know it? (What a stroke of luck NBC has this show to air just two days before its ratings-month blockbuster, "Asteroid," dramatizes that very possibility!) NBC.
"Millennium" (9 p.m.-10 p.m., WBFF, Channel 45) -- Just what is it that makes Frank Black (Lance Henriksen) act the way he does? Maybe you'll find some answers here, as the show flashes back to his first case. Fox.
"Clueless" (9: 30 p.m.-10 p.m., WMAR, Channel 2) -- Could Cher wind up all alone on Valentine's Day? Say it ain't so. ABC.
"20/20" (10 p.m.-11 p.m., WMAR, Channel 2) -- Barbara Walters interviews La Liz. ABC.
"Homicide: Life on the Street" (10 p.m.-11 p.m., WBAL, Channel 11) -- Man, it looks like Doogie Howser grew up to be one pretty bad dude: Neil Patrick Harris, that adorable young doc of years past, shows up as a suspect in a campus murder. On the regular-cast front, Pembleton agrees to his wife's pleas to see a marriage counselor. NBC.
"Nash Bridges" (10 p.m.-11 p.m., WJZ, Channel 13) -- Nash's daughter is hit by a stray bullet at school, so it's up to Nash and Joe (Don Johnson and Cheech Marin) to find out not only whodunit, but where the gun came from. CBS.
"Marry Me" (8 p.m.-9 p.m., Family Channel) -- Have a burning desire to find out how folks such as Jane Seymour, Regis Philbin and Trisha Yearwood met their spouses? Me neither. But for those who do, here's your chance.
"Breakfast at Tiffany's" (8 p.m.-10 p.m.) and "Roman Holiday" (10 p.m.-12: 05 a.m., TCM) -- Valentine evening with Audrey Hepburn not a bad idea.
"Tony Bennett: Live by Request" (9 p.m.-11 p.m., repeats 1 a.m.-3 a.m., A&E;) -- In what's becoming a Valentine tradition on A&E;, the crooner who made San Francisco famous performs live at New York's Sony Music Studios, singing the songs requested by his fans via the Internet or an 800-number. Once again, however, I doubt he'll honor requests for "Your Love Is Like Nuclear Waste."
"Isn't It Romantic" (9 p.m.-10 p.m., repeats midnight-1 a.m., AMC) -- A bunch of celebrity couples who managed to stay married for more than a few years tell how they've done it. Among the subjects: Charlton and Lydia Heston, Eli Wallach and Anne Jackson, Dixie Carter and Hal Holbrook.
