Wolf: When I was given a pin test on Maseches Megillah when I was younger, the Rabbi didn’t actually put a pin through a Gemara. He just pointed to a spot on 2a and had me try to say whatever words were directly beneath it and then estimated (it’s not so hard) where that would be on every later page.
(I wasn’t given this test because I had a phenomenal memory. Rather, the Rabbi was trying to prove the Gadlus of certain people. My classmates knew that I had one of the best memories in the class and I got a grand total of 2 words right. He was showing how big Rabbis are so much smarter than even the smartest of us. He gave the same test to the other smartest people in the class.)
