 The "Thats All Folks" card keeps appearing at the beginning and end.  In  the beginning, after they show the Warner Communications logo, they show  the traditional "Thats All Folks" card that is usually shown at the end.   Bugs Bunny appears in front of it and sniffs and gets rid of the background  and sniffs again then he pushes the words "Thats" and "All Folks"  separately and down comes the word "NOT" in red capital letters underlined.   Then it reads, "Thats NOT All Folks!"  Then Bugs pulls the traditional  opening Warner Bros. logo shown at the beginning.
