It's Wakko's birthday, so Thaddeus Plotz sends a clown to entertain him. Thaddeus Plotz has a phobia of clowns and can barely stand to look at him so he goes to Dr. Scratchansniff for help, where he discovers that Wakko is also terrified of clowns and behaves very unpredicably around them which excites Thaddeus. Meanwhile, the Warner siblings are playing party games and Yakko suggests that they play hide and seek and since Wakko is the birthday boy he is it. As he begins to look for Yakko and Dot the doorbell rings so he goes to answer it and the clown greets him by saying: "Happy Birthday Nice Puppy Boy!" Wakko screams in terror and slams the door in his face. The clown suggests singing a song with him to calm Wakko down but Wakko takes out a mallet and hits him over the head with it caus
