Favorite Happy Days Spin-off Show?

[The Toyroom]

The jury may be out on "Archie Bunker's Place"..: Same sets/writers/cast/characters (with exception of departing Reiner, Struthers, and gaining the young girl), but new name, replacing the 'parent series' as opposed to 'spawning' from it.

Is it still technically a spin-off?

When more action began to take place at the bar instead of 704 Hauser and a whole new set of supporting characters were introduced, including the shark-jumping kid Stephanie I consider it a spin-off....

L&S was the best HD spinoff. Mork & Mindy went downhill the second season, when they added Jay whatever-his-name-is. The most interesting thing about Joannie Loves Chachi was that Vinny Vincent was a staff musician and songwriter for that show, just before he joined KISS.
