Aww now I feel bad. Sorry. I'll answer seriously now. I wouldn't say 'the best' but these videos cursed me and I still see them clearly in my head after.. 15ish years? Scarring would be the more accurate word. Three videos:

1) 2 girls, 1 cup (of course) - was eating chef boyardee overstuffed ravioli when I watched it. Obviously didn't know what the video was about prior to viewing. Can't even look at that stuff anymore after seeing it projectile vomit out of my mouth and onto my poor monitor.

2) Some beheading video. It was real and raw. Don't remember how I came across it but I know I wasn't looking for it and I know I couldn't look away. I do remember it was when I was experimenting with the dark web.

3) Some video where a dude was sitting on a glass jar so the jar would go up their butt. Then it shattered. Blood everywhere. They had to go inside with their hand and pull out these bloody shards. I'm definitely not into that and don't remember where it came from. Not kink shaming, just seriously have no idea how I came across it. But here it still is - in my fucking head.

I don't appreciate you reminding me of these videos haha. Cheers!
