My evidence is in the amount of clearly nonscientific (but rather funny) portions added in the film. For example, a q-tip is hardly a good way to administer a controlled quantity of a substance to a spider. Also, the stuff like the hammock and restraining order kind of clinches the argument. Then again, if you have proof that any of them are real, technically, the burden of proof would be on you to show that it was an actual study.
