 A scene before the Statue of Liberty attack where Venkman tries to get the  ectoplasm to break itself open by singing. He asks a group of firefighters  outside the museum if they know cumbaya. Several raise their hands, and  Venkman has them line up and join hands. He joins them, and they all start to  sing. Meanwhile Stanz watches the ectoplasm through goggles, and sees a crack  smaller than the eye of a needle. Venkman gets annoyed and walks off, yelling  "The Vienna boys choir couldnt get this thing open!"
