Whe I was a kid, we would sing this one song, "Gladly The Cross I'd Bare." I always thought of it as, and even when I was older and knew better, as an inside joke, "Gladdy The Cross-Eyed Bear." I always pictured a cross-eyed bear romping around, as in a comic. I still get a laugh when I think of it.
