Caillou was Upset
Caillou is always upset about things, and the narrator will always let you know about this fact.

Because of this, it has become an inside joke to imitate the narrator and Caillou. This usually goes by a similar format each time, for example: "'Caillou was very upset. He wanted to go the the circus.'"or "'Caillou was very upset. He didn't think Rosie should have gotten two pancakes.'"or "'Caillou was very upset.'""'Caillou: I'm very upset >:('"

Red Car
Red Car is a game where you need to spot a red car. Upon spotting a red car, you must say "Red Car" but you don't have to say it in any very specific tone of voice like with Yellow Car.

After Red Car there are no other car games and it's just over forever.
