I thought that the "Champion the Wonder Horse" song went in part:
Like a shooting star flashed across the sky,
Like the swiftest arrow risen from a bow,
Like a mighty marrow forth he seems to fly...
I didn't know what large, green vegetable marrows had to do with horses but I was used to grown-ups saying incomprehensible things: I just assumed it meant something to them. (I still don't know what that line really was!)
