Caillou dreams that he's a lion tamer and Gilbert is a lion. He then wakes up. He remembers that he is to go to the circus today. He quickly gets dressed. Caillou's dad then comes by the toilet and asks him why he's up so early. Caillou explains that he can't wait to go to the circus. Caillou's dad corrects him - the circus is tomorrow, not today. Naturally, Caillou throws a tantrum. Later, during breakfast, Caillou's dad accidentally grabs hold of burnt toast and starts juggling them. It's then that Caillou gets the idea of playing circus. So they do. Then, Caillou's mom comes downstairs. Caillou's dad asks her if she wants to play the lady that rides the horse. She replies that she'd rather go back to bed. The end.
