I remember the show when it was in production and would watch it often.
As for the charactors, I felt Ted Baxter took a young wife. The couple did have a child so Georgette was much younger than Ted.

Ted must of liked 'em young. His wife on Too Close For Comfort, Nancy Dussault was 13 years younger than him as well.

Indeed-- MTM was 24 when she debuted as Laura Petrie, and Dick Van Dyke was 35 when he debuted as Rob Petrie.

A somewhat obscure example, but on the mid-1960s sitcom "The Bing Crosby Show," there was a 23 year difference between Bing Crosby and Beverly Garland, who played husband and wife. It was accentuated further because Bing looked awfully old for his actual age, while Garland looked quite young for her age. Pretty awkward, unconvincing results.

Did John Becker and Reggie ever become an item? If so, Ted Danson is 16 years older than Terry Farrell.

No they didn't. As I remember they slept together once (I think they were drunk, but I might be wrong). Afterwards, Reggie was so repulsed and disgusted with herself she sold the cafe and moved away, and the character of Chris was brought on. This was because the producers had fired Farrell and were replacing her with Nancy Travis. :mad:
