Seeing tubgirl, goatse, and meatspin put a temper on my curiosity to the point that I can say I've never seen two girls one cup, even though I think it was the most "popular" out of all of those except maybe goatse. Hearing the description was enough to sate any curiosity.

I also know that Rick rolls are wholesome because it replaced surprise links to those. Plus Rick Astley is a genuine treasure and I'm glad becoming a meme didn't end up hurting him.
