I think some of the highlights out of the ones already mentioned off the top of my head are
The Great Betrayal(OG thread merged with People with Skin)
All the random ass topics started by Londa
Spin finding out he's actually white
DrFunk and Londa romance with Spin randomly combo blocking.
Shanedus and Measley Invasion I, II, III
"You aite, brah? You sure?" *power ranger pose*
A random SSJ1Goku appearing to troll black women for no real reason and Satchwar having to go HAM on him
"My Dick Hard, MEET ME SOMEWHERE!"
Operation Blasian Invasion or whatever the Japan trip was called
BGAF taking over random women threads
Ah, memories.
