"Dancing With the Stars" (7 p.m., WLS-Channel 7): Finally, the words you've been dying to hear: Group mambo!

"Jon & Kate Plus 8" (8 p.m., TLC): Kate beats this dead horse one more time, answering viewers' questions. Then, presumably, the show will be over and everyone will have more time for family therapy.

"Real Chance of Love 2" (8 p.m., VH1): Season finale. The stallionaires are down to five lovelies: Doll, Pocahontas, Sassy, Mamacita and Hot Wings. No, I don't know how Hot Wings got her name.

"American Experience" (9 p.m., WTTW-Channel 11): It could be worse. Really. Watch this special on the stock market crash of 1929.

"Cake Boss" (9 p.m., TLC): The new season begins with a cake shaped like an engagement ring box.
