Modders and lovers of mods. What is the most memorable experience of "how long has it been and WTF did I download?!". What unfolded when you loaded the game after so long?

Had a chat with my best friend the other day about this. Ours was left for dead. We both loaded up after a few years. And immediately getting beat to death by My Little Pony (horde zombies) and Fat bastard from Austin powers (boomer), and Shrek (tank).

That is forever in my memories as one of the best moments with my homie.
