I used to believe that in the Rolling Stones song "Shattered" that instead of singing: "Shadoobee, Shattered, shattered" they were singing "Shazbat, shazbat."
It didn't help that I was a big MORK AND MINDY fan, and it REALLY didn't help that when I sang along this way in my father's presence, and then briefly got concerned and asked him if, wait, WAS that right? that he kept a straight face and said yes, yes it was.
