Growing up in Massachusetts, David always used the word bubbler to denote a drinking fountain. So he was flabbergasted during a trip to Southern Indiana when no one had any idea what he meant when he asked where he could find a bubbler. He might not have had that problem had he been wearing a T-shirt from the Wisconsin Historical Society. Wisconsin is one of the few places in the world besides parts of Massachusetts and Rhode Island where people call drinking fountains bubblers. And Australia! This is part of a complete episode.
