|The Unexpected Pest|
Sylvester is forced by his owner to catch mice or he won't have a home to live in. When he has no luck finding a mouse in the house, he goes outside and finds a little mouse, who agrees to the same mouse that Sylvester will catch over and over again, only because he wants to be roughed up in front of his master. It doesn't take the mouse long to realize that Sylvester really does need him alive, and he decides to stop being his fool.
On ABC's The Bugs Bunny & Tweety Show The sequence where the mouse tries to kill himself by dropping an iron on his head, which Sylvester saves him but the iron falls on head in the process was completely omitted.
