Caillou's dad: Public Parenting Enemy #1

I've limited my son to watching only the mildest of TV kiddie fare because fun flashy Nickelodeon and Cartoon Network stuff makes him jumpier than SpongeBob on speed, but while the likes of "Arthur" and "Zoboomafoo" and "Little Bear" do keep him calm, there are always complications. Right now, for example, Caillou's dad has become the exemplar of all that parents should be and all that I am not. 'Cause see, Caillou's dad says yes to everything. No matter what Caillou wants to do, his dad finds a way to make it fun and safe and cool and cartooneriffic. Why, my son would like to know, can't I be more like Caillou's dad? Why can't I say yes all the time? I try to explain that we only see a tiny part of Caillou's day, and maybe his dad says no all the time in between; I try to explain that good parents have to say no sometimes; I try to explain that it's easy to say yes when you're a cartoon character; I try to explain that Caillou never asks his dad if he can listen to 50 Cent. But it's no use. Caillou's dad is cool, and I'm a killjoy. You've got to ask yourself, though: What did Caillou's dad say yes to that caused all his kid's hair to fall out?
