Do these events happen before or after Fonzie jumps the shark?

The Happy Days episode "Hollywood: Part Three" features one of the most legendary moments in television history.

In what has since become short-hand for "The moment a show becomes bad," Arthur Fonzarelli water skis over a shark. Yes, that's right. Milwaukee-based leather orphan The Fonz somehow finds his way airborne over a great white. It's amazing. It's ridiculous. It's probably a lot worse than you remember.

So, because it's such a watershed moment, and has become a part of the lexicon, we want to zoom in and see how well you know the rest of Happy Days. See if you can tell us whether these events happened before or after that fateful jump!
