Does anyone know all the episodes Anson Williams appeared in during the last Season of Happy Days? and what he did in them?

That's a good question, since he was still in the credits that year, his appearances weren't guest appearances so it doesn't say in the episode guide. Does anyone else know how many episodes Potsie was in during Season 11?

The only episodes that I can recall were the 2-part episode when Richie and Malph returned from the army. I don't know of any others.

Potise appeared in 4 Season 11 epsiodes that I know of:

"Where the Guys Are" (Episode # 236)
"Welcome Home, Pt. 1" (Episode # 237)
"Low Notes" (Episode # 248)
"Fonzie's Spots" (Episode # 251)

There may be a few others, but those are the only ones I'm sure about. I sure hope they rerun Seasons 8-11 on Nick-At-Nick, so I can get every episode on tape.

The saddest thing about this is that he wasn't in the last episode where Joanie marries Chachi and Richie comes back for the occasion. In Seasons 1 and 2, Richie and Potsie were inseparable and at the end, he doesn't show up for one of the biggest days in Richie's life.

I'm sure this had a lot to do with Anson Williams himself getting tired of his diminishing role on the show. He used to be an important part of it but by the time Richie and Ralph left for good, he had little to do but hang around Mr. C all day and act the 'doofus' role. That had to wear on him after a while.

Good point I also noticed that Donny Most wasnt there either I thought that was sad That Neither one of Ritchies Old Pals Except The Fonz Ofcourse were in the last episode. that reminds of when they didnt bring back Abe Vigoda in the last Barney Miller show They only had a Clip of him from the 3rd season.:(

Well, at least Richie was in the final episode.
