Albert's Place

I think I have asked this numerous times over the past couple decades to various friends and collegues... now I ask here:

"What the fuck ever happened to Richie and Joanie's older brother Chuck on 'Happy Days'? Seems he was in the first episode, then vanished off the face of the earth, never to be seen or heard about again!"

When they zoom out on the outside of the burger place at the end of Episode 1, instead of saying "Arnolds", it says "Arthur's"......

Who woulda thunk I'd get the most responses in ages commenting about the "Happy Days" set I just got!
