Wow this whole thread turned mostly into a Freak Out Kid debate against me.
Stephen does have freak out tantrums that his brother started off by catching on video, then they exploded online super viral. Many say it's fake after watching it once or twice, no evidence, just their gut feeling that becomes fact.

I don't care if all of you reading this think Stephen's videos are fake, who cares, it's your loss for not being able to comprehend the fantastic comedy of them. The comedy that they are real tantrums is why they are so viral.
John Lakewasamo (sp?) and many others have tried to duplicate those videos and fail miserably, because you can't fake that video game drug induced maniacal rage. "CAN'T BE FAKED", go ahead and try it and get back to me.
