My favorite threads, from here, have been the ones where I saved sites to my favorites (there's been a few).

The Word Association thread was never used, by me, to increase post count. I'm sure I would've found another few threads to post 100 in. It was funny to see what someone came up with after a certain word (in some cases).

The worst thread, the only one to make me cringe, was the one with 15 close-ups of a penis.
