"Merge" (7 p.m., Lifetime) is one reality show that actually deals with a real problem -- what to keep and what to throw out when newlyweds move into a new home. Host Lisa Rinna makes sure that really bad stuff gets tossed into a big shredder, while the merely surplus is donated to charity.
"The Making of 'The Passion of the Christ'" (8 p.m., Pax) was made to help publicize Mel Gibson's film, but it may be of greater interest now that the movie has been seen and debated. It's repeated tonight as Christians observe Good Friday.
Host Jon Favreau chats with some of the people from the movie "Jersey Girl" -- director Kevin Smith and actors Jason Biggs, George Carlin and Stephen Root -- on "Dinner for Five" (10 p.m., IFC).
Mother-daughter diva duo Joan and Melissa Rivers return in the first new episode of the makeover show "Head 2 Toe" (6 p.m., Lifetime). Hosted by Tanika Ray, the program gives two women -- best friends, co-workers, siblings and tonight, the Rivers pair -- a chance to make each other over as beauty and fashion pros stand by to help.
If you're a latecomer to "Deadwood" (8 p.m., HBO), the riveting new cable Western, here's your chance to catch up. The first three episodes will be repeated back-to-back. New episodes continue to air Sundays.
