Please fill me in!
Something like this:
"So there is a guy on my train ride every day from Monsey to Brooklyn and he always gives me attitude. So one day, I go to the conductor in advance and I pay for the ride, making up with him that when he goes around asking for money, I will put my hand in front of my eyes and pass my finger from right to left, and he should then say, 'okay, you can go for free today.'
"So the conductor comes up to me and I pick up my hand and slide it in front of my eyes, and the conductor says, 'okay, you can go for free today.' The attitude guy is watching wide-eyed, and he comes over to ask me what I did. 'You don't know? If you do this trick, they have to let you ride for free!' So he begged me to teach him the trick. 'It's a very precise maneuver, but if you pay me, I'll teach you,' I told him.
"So he paid me and I sat there to teach him, driving him completely crazy. 'no, you have to do it a little higher.' 'hey, that's too fast.' 'no, a drop lower.' Eventually, I had enough fun, so I told him that he perfected it, and I got off the train.
"The next day, as soon as I got on the train, he came running over to me red in the face. 'hey, on my way home yesterday, I did the maneuver, and the conductor looked at me like I'm nuts. I kept doing it and he threw me off the train!' So I looked at him and said, 'you did this on the way
home?' He nodded. 'You missed the boat,' I said. 'This only works from Monsey to Brooklyn. When you are going from Brooklyn to Monsey, you have to slide your finger from
left to
right!'"
Yes, it doesn't sound funny, but again, my name is not Yankel Miller. I believe there is a video of him saying this at a sheva brachos and Rav Chaim Kanievsky, who was in attendance, is laughing away.
