Potty Mouth Littlefoot

I was looking for a Littlefoot video online for the girls and found this. It's Littlefoot and friends doing Kyle's Mom's a Bitch, from the Bigger, Longer, Uncut South Park movie. Maybe this is only funny to me because my kids love little foot and I've spent far too much of my life watching it with them. The Littlefoot I know would never say things like this.

It appears there's a whole genre of kid culture gone PG on YouTube. Makes me want to take an episode of Arthur and turn it into Glengarry Glen Ross. That would be fun.
