When the Rebbe came into Shul for hakofos (on the nights of Shemini Atzeres and Simchas Torah), he would put his siddur on his shtender, then turn around to the assembled crowd, start a joyous niggun, clapping his hands, dancing and encouraging the crowd to sing and dance.
Once, when the gabbai announced the procedure of how the pesukim of Atoh Horaiso will be recited and who will have the kibudim (honored) - he announced that the first passuk of the Atoh Horaiso will be said by the Rebbe...the second passuk will be said by the Rebbe's brother-in-law, the Rashag; the third passuk will be said by the Rebbe's chief secretary, R. Chodakov. All the following pesukim (until the last), anyone can buy and honor any relative or any "gutte freint" (good friend) whom he wishes to honor...
Hearing this, the Rebbe turned around with a wide smile on his face and commented: "Ich bin oich a gutterr freint!" (I am also a good friend)!
