Mr. Feeny said he been a teacher for decades on the show. I think he said over 30 years in one episode, so I was wondering how old was he supposed to be on the show. He looked late 50s or early 60s at most?

Although Mr. Feeny talked about not being able to have shoes that didn't mark the gym floor when he was a boy due to it being WWII (which would have made the character having been born c. 1932), William Daniels was actually born in 1927. So look up the year/s the show was on and do whatever math you'd like on this! :cool:

I guess he be in his 90s if he was born in the early 30s.
