Dr. Epstein was a renowned physician who earned his medical degree in his home town and then left there to live in New York.
Later he was invited to return to his birthplace to give a speech. As he placed his papers on the lectern they slid off onto the floor, and when he bent over to retrieve them, at precisely the wrong instant, he farted and the microphone amplified it throughout the room. He was embarrassed but regained his composure to deliver his paper. As he concluded, he raced out the stage door, never to be seen in his home town again.
Decades later, when his elderly mother was ill, he returned to visit her. He reserved a hotel room under a false name, Levy, and arrived under cover of darkness.
The desk clerk asked him, "Is this your first visit to our city, Mr. Levy?"
Dr. Epstein replied, "Well, young man, no, it isn't. I grew up here but then I moved away."
“Why haven't you visited?" asked the desk clerk.
"I did visit once, many years ago, but an embarrassing thing happened and since then I've been too ashamed to return."
The clerk consoled him. "Sir, while I don't have your life experience, one thing I have learned is that often what seems embarrassing to me isn't even remembered by others. I bet that's true of your incident too."
Dr. Epstein replied, "Son, I doubt that's the case with my incident."
"Was it a long time ago?"
"Yes, many years."
The clerk asked, "Was it before or after the Epstein Fart?"
