TV picks for July 7-11:  Betty White, "Dangerman," "Crown Chasers" Ray Harryhausen

In a new edition of "Celebrity Wife Swap" (7 p.m., KSTP, Ch. 5), Nia Peeples and Tiffany trade places. Immediately afterward, they ask if it's possible to switch decades so they can relive the '80s, an era when they actually mattered.

In "Dangerman" (9 p.m., BBC America), Jonathan Goodwin shows off his ability to dangle from skyscrapers and escape from handcuffs while hanging upside down from a helicopter. But while the stuntman is big on bravery, he's low on showmanship. Yes, the feats are near deadly, but some are just deadly dull.

Will Lou Grant and Sue Ann Nivens ever give in to their undeniable lust for each other? "The Mary Tyler Moore Show's" would-be lovebirds get another chance when Ed Asner guest stars on the season finale of "Betty White's Off Their Rockers" (7:30 p.m., KARE, Ch. 11).

Turns out pageants aren't just for Little Miss Sunshines. "Crown Chasers" (9 p.m., TLC) follows five women, ages 30 to 52, who compete in beauty contests around the Denver area. The "frenemies" will do anything to take home the winning sash — with the exception of adopting Honey Boo Boo. There's only so much a contestant can do.

A great documentary on special-effects whiz Ray Harryhausen aired on Sony Movie Channel this year, but there's nothing quite like seeing his films from start to finish. The artist, who died in May, is honored with a marathon, starting with the 1963 landmark production "Jason and the Argonauts" (7 p.m., TCM).
