For the love of a variable!

With the wealth of “Scientific” shows out there that seek to discover answers to one question of another… is there anyone else besides me that sees the blatant flaws in their “scientific experiments”?  (I’m sure I can’t be the only one!)  I dunno, just takes the fun outta watching something when you know they’ve left this huge, gaping variable outta the equation and then claim they have “proof.”
