See how the cast of 'Happy Days' changed from their first to last episodes
A lot can change over the course of 11 years.
When Happy Days premiered in 1974, no one could have predicted its success. The hit sitcom sat atop the ratings, generated a few popular catchphrases, and spawned two massive spin-offs in the 1970s (not to mention some less successful ones).
Of course, such a long run meant some substantial changes. Main characters left the series, new ones were added, and sharks were jumped along the way. Airing a decade apart, the first and last episodes of the series could easily be two separate television shows.
Here's a look at how some of the characters — even a minor one — changed from their first episode of the show to their last one. It's amazing how 11 seasons will change you.
