Reb Itche der masmid was once supposed to be eating the shabbos seudah by the Frieredige Rebbe. After davening, when it was time to make kiddush, the Frieredige Rebbe didn't make kiddush because he was waiting for Reb Itche. - Rabbi Aronow said: the Rebbe was a "gentleman", and wouldn't make kiddush without his guest! After some time went by, and Reb Itche didn't show up, the Frieredige Rebbe sent someone to see where he's holding in davening. The messenger returned and said that Reb Itche is holding ויברך דוד. So the Frieredige Rebbe said: איטשע דארף חאפען א שנעל, אבער עס דארף זיין וועמען. And he explained, a shnell was a flick in the nose, and he was saying that Itche deserves to get punished, it's not appropriate to leave the Rebbe waiting. But he's after all Itche, we don't have the person who's worthy of giving him the schnell. [ולהעיר A more known nusach is that the Frieredige Rebbe responded that it's impossible, Itche can't be holding by vayevorech dovid. Either he's holding by vayevorech, or he's holding dovid. Either they were 2 separate stories וא"כ נצטרך לומר דבב' הפעמים אחז ר' איטשע בדיוק אצל ויברך דוד (!) Or that it was one occasion, and the Frieredige Rebbe said both things ומר אמר חדא ומר אמר חדא ולא פליגי]
