Mi-Bnei Banav Shel Haman Limdu Torah Be-Bnei Brak (Sanhedrin 104b)
This is simply outrageous.
I can't help but think of the late Lubavitcher Rebbe, whose main antagonists included Satmar and Ponevezh, laughing in his grave as those two movements are fighting was of succession (literally) while his, despite much internal tension, remains stronger than ever.
It provides a different spin on the Chabad melody after which this post is named. The translation of its words are as follows:
"The grandchildren of Haman taught Torah in Bnei Brak. We are victorious."
