It's been one of those times where a certain actor or actress keeps popping up in different shows even though you are not trying or looking for that person. The only thing I was selecting was Christmas episodes of shows I've been watching all year.
So far this week I've seen Will Wright on each Christmas episode I've seen so far, The Real McCoys as a hock shop owner, Ozzie & Harriet as the old guy who sells his piano to the Nelson boys, December Bride as the grouchy neighbor & Andy Griffith as Ben the Scrooge. Will Wright sure got around in his old age. He really was the perfect grouch. I think after he died Charles Lane must have got all the grouch parts Will might have done.

He wasn't in any of the Dennis the Menace Christmas episodes, but was in the series as Maryvale the garden center grouch. IIRC in the piano O&H episode he wasn't a grouch for a change.

I don't think there was a sitcom of the era that he wasn't on. In early Leave it to Beaver he was one of the firemen.
