Traumatized by his circumcision, Leonard Cohen prefers the Twist!

At 9 years old, at his father's death, Leonard performs a neurotic ritual in which he unconsciously takes a symbolical revenge for his circumcision.

“I went to his closet and I found a premade bow tie. I DON'T KNOW WHY I DID THIS,... BUT I CUT ONE OF THE WINGS OF THE BOW TIE OFF and I wrote something on a piece of paper—I think it was some kind of farewell to my father—and I buried it in a little hole in the back yard. And I put that curious note in there. . . . It was just some attraction to a ritual response to an impossible event.”
