For whatever reason, Jack brought along a can of Silly String, which he used at strategic moments in a relatively harmless effort to cause consternation amongst his bandmates. Whatever fondness I personally held for Silly String ended with:
a) The complete and utter ruination of my first car's interior as the result of a three-way Silly String battle in 1985; and
b) Me becoming a parent and recognizing Silly String to be an evil, messy and destructively pointless waste of life force...the latter opinion I'd imagine was shared by the staff of O'Bank's, who got to clean up the mess!
