On the topic of debunking pseudoscientific hoaxes, Stan Winston (the multiple Oscar-winning fx genius behind Jurassic Park, Aliens, The Terminator and many, many moore) once appeared on television to debunk the infamous Patterson "Bigfoot" footage. He said it was a man in an ape suit that was so crappily designed, he would have instantly fired anyone in his shop who tried to hoist it on him.
Those of us of a skeptical inclination are not surprised by this, but I'm sure that the reality-based community is disappointed to learn that the aliens weren't for real :-)
He'd been even MORE upset if, instead, they'd tried to FOIST it on him!
