I just got done watching the Happy Days 2nd Anniversary show when it is Fonzie's birthday. At the end when they show the "Sit On it" clips. There is one where Marion says "Sit on it Fonzie" and Joannie says "Everyone duck" Then Fonzie asks who said that. What show was that from?

That was from the episode, where Arnold gets married, and that happens when Fonzie refuses to be best man, due to the "Fonzarelli Curse." One thing I can't figure out is, they showed that clip in the second anniversary show, but, that episode wasn't even yet out, because the anniversary show was seen in January of that season, and the wedding episode didn't air until the close of the season in March, and that's obviously how Arnold left the show.

How I know the facts about what I posted above, is because, I once came across an episode guide of "Happy Days" with their original air dates

Thanks for the info. http://www.sitcomsonline.com/ubb/smile.gif

The reason for that is because Arnold's Wedding was the last episode to air that season but The 2nd Anniversary Show was the last episode they actually made that season. Arnold's Wedding was actually about the 17th episode made/produced that season.

I do remember that some of the episodes were shown in backwards order, during their original run, for instance, during the final season, there is an episode where Fonzie is charged with striking a student, and, when i saw it in reruns, I found there was mention about Fonzie accidentally punching Howard in a hotel room, and the episode that featured that didn't air until the following week, in it's original run
