A childhood belief about songs

My dad has always been a clever and imaginative guy. When my brother and I were around 7 or 8 years old, we were riding in the back seat of the car. My dad in the driver's seat started singing, "Wellllll, who put the bop in the bop-she-bop-she-bop, who put the ram in the ram-a-lam-a-ding-dong...." My brother and I just thought that Daddy was the weirdest human being ever for inventing such a silly song as that. And no matter what he or my mother in the front seat of the car said, they could not convince us any differently. It wasn't until at least a couple of years later (maybe more?) that I finally heard the song on the radio and it dawned on me. I stood there for a full two minutes, dumbfounded that it's actually a REAL song!
