I remember a particular NPC in Jersey once. Janosz (pronounced Yan-osh), the plant grower. He walks around town and spread seeds down, seeming oblivious to the mutant plant things that sprung up, every few steps he's stop and scream "Janosz! Janosz is here!" After some rp and fighting, I had a question for John, so I walked up with my hand on my head and whisped, "John, i have a question." In the loudest and worst accent ever, throwing up his hands and raining seeds everywhere.... "There is no John.. Only Janosz!" That broke me, most of the NPCs and a few PCs. That's is one of my fondest memories of John, you never know when he was gonna make you laugh, you just knew it would be often, and always funny.
