Something I've done recently was to go through all of the boards and check out the explicitly closed threads. Good times there.

My personal favorite was a poster who was trying to get people to do his work for him. After being called out on it, he went on a mini-rant while still trying to get someone to do his work. That post ended with this sentence:

From you nerds, I would like some better and optimized logic than those I posted
There's something hilarious to me about calling the people you're trying to get to help you "nerds."
