Okay, so it's been a while coming, but here it finally is.
Funtime Thread of Humor and Mirth (and Junk)
I think just about every forum has its random stuff/joke threads and this would definitely be ours at the moment. You'll find a lot of selected YouTube clips here, as well as some other stuff.
So if you're in the mood for a laugh (or if you just want to contribute your own craziness), this thread comes highly recommended.
