^But the episode I cited was hardly the first time Happy Days used the word. I can't say for sure if it was used from the start in 1974, but I have no reason to believe it wasn't.
The thing about etymological citations is, the earliest documented reference is never the actual first reference, since new usage generally starts out in everyday conversation that isn't written down or recorded. If both shows used the term around the same time, it's probably because it was already starting to catch on in everyday life.
