I'm guessing Venkman was originally wearing a proton pack in the commercial - hence the straps at the beginning and him pointing to his back at the end. Why take this out?
Yeah, right.

And to the poster who noted Winston not being in the commercial, by the way its shot (cutting off the top of venkman's head) I'd say he's probably manning the VHS recorder.
But poor Winston was in the GB2 commercial
