The “Round Tuit” is a circular, coin sized disk often made out of wood, but could be other materials, with the word “TUIT” printed or engraved. Sometimes they’re accompanied by additional engravings that say something along the lines of “This is a Round Tuit. Guard it with your life, as Tuits are hard to come by, especially the round ones. This is an indispensable item. It will help you become a more efficient worker. For years we have heard people say, I’ll do it as soon as I get a Round Tuit. Now that you have one, you can accomplish all those things you put aside until you got a Round Tuit!”
I learned about Round Tuits when I was a child, perhaps around 6 or 7, and barely understanding the concept. I discovered one laying around at my grandma’s house and asked what it was. My mom explained the idea, and told me how my grandpa used to own them and pull one out whenever someone would say, “I’ll do it when I get around to it.” We used to have one wooden one and one red plastic one, and for a while as a kid I would hold on to them in case I had the opportunity to give one to somebody.
My interpretation of this folk object is that it’s merely punny humor in the form of an item and right up the alley of my parents and grandparents. I can see how an object like this would be a funny interjection in a conversation and could also even fall into the category of dad jokes.
