Caillou has a special friend named George. He's special because only Caillou could see him. Caillou suddenly wants to have a race. On winning the race, Caillou knocks over a flower pot. While thinking it over, Caillou decides that it was George's fault that the flower pot broke. Later, while eating, Caillou talks about George some more, and says that George lives in the basement. But he comments that George is his favourite friend in the whole world. But because he spent too much time talking about George, he hardly ate his lunch. Later, Caillou's asked about the broken flower pot. He claims that George did this. But Caillou's dad knows better - George is to Caillou what Nadine is to D.W. in Arthur. So, he manages to talk Caillou into admitting that he also had something to do with it. He also talks Caillou into helping him clean up. Later, Caillou talks about George some more while playing on the swing with his dad. (thetvdb.com)
