OMG, how could you all be so naive. Wolf took you all in.
He was referring to the old joke about a new Rabbi who comes into a shul. As he begins his position, the night of Pesach approaches. The Chazan begins to say Hallel. A fight breaks out. Some say we do say Hallel, some say we don’t. The new rabbi asks, what is the minhag of the shul, what did you do last year? Some balabatim yell we always said Hallel. Other scream, Liars, we never said Hallel.
The new Rabbi is totally perplexed how to handle this. After Pesach, he calls up the old Rabbi who had retired to Florida. He tells him, there was a big fight over Hallel on Pesach night. What is the established minhag of the shul? The old Rabbi tells him, that is exactly right, the minhag is to fight over whether to say Hallel.
