S1·E28 Caillou is a Clown

Caillou is very excited because he’s going to a parade with horses, drummers and clowns. But Rosie is afraid of clowns so Mom isn’t sure it’s a good idea to go. Caillou is upset because he thinks he’ll miss the parade just because of that. And then he has a good idea: If he shows Rosie that clowns are just people wearing silly costumes, she won’t be afraid anymore.
