Most people don't even know what makes those Steve Balmer videos so funny (monkey boy and developers).
For example IIRC 21 seconds into the monkey boy video he lands akwardly on his leg and yelps like a little girl then limps afterward.
The developers video is funny because he's trying really hard to get his audience to clap. He almost faints but his audience takes pity on him and starts to clap. Balmer is so proud of his accomplishment he congradulates himself.
Of course this clip is even funnier!!!
