<human>: Unfortunately I don't have very many details, which could make this difficult. I know for sure he was on the show demonstrating how to make pottery. He's pretty sure he was on the same episode as a glass-blower, as well. 
He said it was around 1971, but my grandma thinks it couldn't have been '71... she says he was overseas at the time. He was only home for a year after serving as an Airborne Ranger in Vietnam. He was having a hard time re-adjusting to "normal" life after that, so he went back into the army a year later. Since he was having a difficult time while he was home, I figure it's possible he's remembering the date wrong. That being said-- I think he still probably remembers better than my grandma... so I'd stick with 1971, haha.

He was working at Silver Dollar City in Branson, MO (doing pottery) when they found him & asked him to be on the show. Apparently they found a lot of the show's guests there, though.
If anyone on Reddit can figure out which episode it was, we will be forever grateful! My grandpa just acted like it was no big deal and he didn't know why we were so excited about it, lol.

Summarize the given text in a few sentences.
<bot>: My grandpa was on Captain Kangaroo in roughly 1971 doing pottery. Same episode as a glass-blower. Can anyone help me find the episode he was in? Thanks, Reddit!!
