I came across these videos in the past couple of days, and I thought they were great.
This first one is from Sesame Street. I don't remember Sesame Street being this funny. I was laughing almost the whole time, especially when Cookie Monster says, "...Frog..."
The next video is also from Sesame Street and it is really cute. It is a good representation of the happy side of parenting.
The third one I can't embed, but it's a video of a little kid giving an impromptu motivational speech after learning how to ride a bike. It's pretty great.
