In 1985, our grade school was hosting a year-end tournament for 6th grade boys and girls. In the boy's tournament, a player ran right off the bench to sub in for a player and the head coach got whacked. The coach then argued about the original tech and racked up 4 more technicals before he was told to leave or risk forfeit.
With the rule changes that have occurred since then, I doubt I will ever see an individual get 5 technicals in a game again.

Aside:That was a weird year for the tournament in general. We had a coach on the girls side accuse my dad (who was the tournament scorekeeper for some of the games) of getting fouls wrong and she even wanted to protest the game. Since the AD suggested using different colors for each half after that game, that is what made me adopt the convention of different colors each period (something that has helped when coaches want to argue about timeouts taken or who fouled when).
