"Diff'rent Strokes:" "What `chu talkin' `bout Willis?"

"Webster:" The dumbwaiter.

"Facts of Life" and "Golden Girls:" Four ladies share problems and living quarters in a complex love-hate relationship, all the while giggling and coping with the facts of life.

Besides a generation gap of about 50 years, what makes each show special?

"Facts of Life:" "Edna's Edibles"

"Golden Girls:" St. Olaf and "Picture it--Sicily, 1932."

Third time's a charm: "227" (consider this: have you ever seen the headstrong, vain Blair Warren, Blanche Deveroe and Sandra Clark [a.k.a. Jackee] at the same place at the same time? How about the wise-cracking grannies Edna Garrett, Sophia Petrillo and Pearl Shay? Coincidence? I think not.)

"Mr. Belvedere" and "Mama's Family:" Hard-headed title character (Belvedere, Mama) maintains the sanity of a household through wit and sarcasm, dealing with stupid patriarchs (George Owen, Venton Harper) and mischevious family members (Wesley, Naomi).

Unique?

"Mr. Belvedere:" End-of-show diary passages

"Mama's Family:" Iola and her gingham dresses.

"Family Ties" and "Growing Pains:" Living the lives of two working parents, a smug older brother (Alex Keaton, Mike Seaver), the self-conscious middle sister (Mallory, Carol) the forgotten third child (Jennifer, Ben), one annoying friend (Skippy, Boner) and a random fourth child who emerges as the series starts to wane (Andrew, Chrissy).

How'd we tolerate both?

"Family Ties:" Alex and his parents don't share views on politics.

"Growing Pains:" Mike and his parents don't share views on skipping class.
