The second video pisses me off. That's really messed up.
As for the first video, it reminds of this time I knew this one guy that had a phobia of hunchbacked people, specially Quasi Motto (SP?) and then one of my friends put a back pack in the back of his shirt and pretended to be him and scared the crap out of that one guy. He deserved it for trying to be a badass. As for scaring the little kid, it is kind of smurfed up.
