Being a huge Jackass fan gives me a high tolerance to disgusting things. Seeing over 5 hours of constant vomiting and gagging, I'm like immune to disgusting stuffs. On tv.
But then I saw this steve-o clip from jackass 2.5, and it creeped me out. I mean it's not REALLY disgusting compared to some other ones but there's a certain aspect of it (which I could not grasp) that makes me, make faces.
Video yourself watching this. And then watch your video. You'll realize that you made weird faces. Teeeheee.
EDIT: I totally forgot about the classic Goldfish trick.
Saw this on tv.
