Well I've had a number of good moments, but I can only recall one right now. It was when I and spazzyman first discovered that it was possible to remotely rename people in a jj2 server by doing some packet editing. Shortly afterwards I made a small test proggie in VB that allowed me to do just that. It was an early version of renamer programs that you get to see today. And I couldn't resist testing it. So I went into this CTF server where a number of people were playing and renamed some guy who was chatting with the server to... I think it was a bad word or it must have been some other name that the server hated, I can't recall. Then slowly the two started cursing at at each other really hard and the drama ended with everyone in the server getting banned (me too).

It's not something I would do today, but it's still a laugh to remember the old days.
