It's only canned laughter, think most real people would react differenly once over the age of 14 (developmentally speaking).
I've always seen that video and just assumed the pilot was being a dick. Thanks for clearing that up Blender. There's often more to most situations than meets the eye. It reminds me of a CRM course I went to a while back where the trainer showed Dennis Kenyon's accident in a similar light: the consequences of flying foolishly. That he had no idea of who Dennis Kenyon is and the circumstances was plain pitiful. But hey, ignorance is bliss.
