How the fuck can you find the first one amusing? Seriously, if you find it funny you're a fucking psychopath.
Fucking stupid Americans, I can't believe anyone would do that to their child. And WTF, after they see that he's sad and that the so-called joke was a failure they laugh even more? And at the point he's going to cry they leave the room? What a messed up christmas/birthday party.
Btw, did the cam recorder say "Look at the camera and cry" at some point? I think I heard him saying that.
EDIT: on the second vid looks like the girl is faking it. lmao.
