In Ghostbusters 2, why is the patch on the uniform giving a peace sign? Obviously in the context of the real world the new logo makes sense. However, in the reality of the movie, why would they make a patch that basically looks like a symbol meaning "No ghosts offering peace"?
I'm guessing the (rather flimsy) in-movie excuse is that it's supposed to illustrate they're back in business, which is emphasized in the (deleted) full version of their in-movie TV commercial:
STANTZ: That's right -- Ghostbusters. We're back and we're better than ever with twice the know-how and twice the particle-power to deal with all your supernatural elimination needs... And to celebrate our grand reopening, we're giving you twice the value with our special half-price 'Welcome Back' service plan.
I never thought of this as a peace sign; I always just thought of it as two fingers for the number two, as in "Ghostbusters II". This makes more sense in the context of the original poster.
