1. Happy Days (1974-1984) - Fonzie, Richie, Potsie and Ralph were a huge part of 70s pop culture, and their show put Garry Marshall (and his family) on the map, and spun off a few more shows.
2. Laverne & Shirley (1976-1983) - By far Happy Days' most successful spin-off, Garry's sister Penny and Cindy Williams actually eclipsed the parent show for a couple of years.
3. Mork & Mindy (1978-1982) - Robin Williams broke out, and shot into the stratosphere with this Happy Days spin-off, and then sputtered out after inexplicable executive meddling.
4. Angie (1979-1980) - Rather short-lived for a show with a lot of promise. Robert Hays (Airplane!) and Donna Pescow (Saturday Night Fever) starred with Doris Roberts (Everybody Loves Raymond). Also a death by executive meddling.
5. Bosom Buddies (1980-1982) - Can you believe a show starring Tom Hanks would only last two seasons? Or that co-star Peter Scolari often out-shined him in the talent department? It's true!
6. Joanie Loves Chachi (1982-1983) - One of television's punch lines, this spin-off of Happy Days was actually (briefly) a hit. And then collapsed.
7. Perfect Strangers (1986-1993) - Balki wore thin after several seasons, but for the first few, this was a really fun sitcom, mostly due to Bronson Pinchot.
8. Family Matters (1980-1998) - Spun off of Perfect Strangers, this show was--to me--horrific. But to kids of the time, it's kind of their Happy Days, and apparently Steve Urkel is their Fonzie. Whatever. . .
9. Valerie/Valerie's Family: The Hogans/The Hogan Family (1986-1991) - Originally a starring vehicle for Valerie Harper--whose character was ultimately killed off in an awful contract dispute--ultimately it became The Jason Bateman show despite its various other titles, and new star, Sandy Duncan.
10. Step By Step (1991-1998) - Suzanne Somers and Patrick Duffy in a pointless, rice-cake of a sitcom. Just bland as hell, but again, if you were a kid at the time. . .maybe. . .it was just okay?
And with that bit of fluff, we'll call it a day. But since Monday's over, I'll wish you all a happy short work week, with a faster weekend!
