1. The television series 'Arrested Development' was based on events that occurred in Carl's life when he was 14 and 15 years old. Carl never received credit or compensation for this, and is still locked in a complicated legal battle with the producers of the show.

2. The new movie, 'Superbad', is based on Carl a few years after the television series. Unlike the show, this movie has Carl's authorization and support. The movie was originally going to be entitled 'Carl Quest: The Movie', but market research showed that the target demographic generally dislikes people named 'Carl'.

3. Carl is an internationally recognized mathemagician, as can be evidenced by these flawlessly completed sudoku puzzles.

4. Brian, Carl's nemesis, was, under a pseudonym, a somewhat well-know child star in the early nineties. He is best known for his work in 'Little Rascals', 'Little Giants', and 'Jack'. He now lords over the goons in his town and generally causes as much trouble for Carl as he can.

5. Carl is one of the few people who can claim that he has won a fight against his dad, and is also one of the even fewer people who has the event on video. Unfortunately, it was found to be in violation of youtube's terms of service and was removed.

6. Carl's bedroom has a mysterious 'bermuda triangle' effect, except that instead of affecting airplanes, it affects girl's underwear.
