Reality check

Just four months till ‘American Idol.’ For now, try scratching that itch with celebrities who dance and sing. Not enough?

Globe trotters: Basking in its millionth Emmy win, “The Amazing Race” moves time slots again and revs up for another season of running around the world like only crazed, sleepless Americans can. CBS, 8 tonight.

Can’t we all just get along? On Thursdays, CBS is already cooking up controversy with a “Survivor” split along racial lines. Meanwhile, NBC’s “The Biggest Loser” is split along state lines this season: Will the South finally beat back the North on the scales? 8 p.m. Wednesday

Who’s your mommy? A beauty pageant mom -- can you say “penchant for perfection”? -- trades with a mom who thinks cleaning is overrated. Oooo, the drama that is “Wife Swap.” (ABC, 8 p.m. Monday)

Get out your handkerchiefs: The deserving get their due and viewers get a good cry when the new season of “Extreme Makeover: Home Edition” premieres on ABC at 7 p.m. next Sunday.
