This is about as mundane and pointless as it gets, but:
I’m watching the (NFL) game while posting in various threads. During a commercial, I got up to go to the bathroom, and as I was doing so, I suddenly started singing:
“Yippee kai ay and a yo ho ho,
We’re sailing along on high.
Just Molly and me
O’er the lone prairie
In our wagon way up in the sky.”
I had no idea why I sang it. I had no idea where it came from. I had no idea what it meant. After some googling, I found that (with a few minor differences) it was from a cartoon called “The Saga of Windwagon Smith,” which appeared on Walt Disney’s Wonderful World of Color in 1961, when I was a tot.
So I must have seen it some 54 years ago. To the best of my knowledge, I have never heard, seen, or thought about it since then.
