Remember that insanely awesome cross-canyon rope swing video Liz wrote about?  Did you ever wonder how on earth those adrenaline junkies got the nerve to hurl themselves off a cliff?

Video: Charming guy pushes his terrified girlfriend off a cliff

Well, this behind-the-scenes video demonstrates that at least one member of the thrill-seeking crew never got up the courage.

Instead, her boyfriend (now ex-boyfriend?) actually tricked her into trusting him before he shoved her off the ledge.  Who says chivalry is dead?

Boys, I recommend you NEVER try something like this at home.
