One of the most mentchlidik and torahdik characters sitting at the King's gate was Shushan boy.
"I just cut an onion in half with a milk knife but I want to cook the onion with meat. What do I do, Shusan boy?"
"Cut off a klipah from the cut sides of the onion with a pareve knife and you're fine".
"Thanks, Shushan. You're metchlidik and torahdik."
"Bless you, sir".
Little did anyone know that whenever there was a call for help....
"OY! OY VEY ZEMIR"
Shushan boy became in real life that member of the Beis Din Hagadol, Mordechai!.
