all I can say after watching the two girls 1 finger thing is, just what the fuck exactly is wrong with the Japanese anyway?! Good fucking god!!
After 2 girls, 1 cup, and in true Japanese fashion, they had to take something American and make it better.
After watching the reaction video a second time and focusing on him (I was intrigued that he was so unfazed), he blinks once at the beginning of the video but then not again until they are done watching. It makes me think he has his eyes out of focus.
