First here is a video my kids and I watch frequently. See we are all huge Harry Potter fans.
Next is another cute video especially for Lego and Star Wars fans. It's a complete summary of all the movies done with Lego figures. Just over 2 minutes long.
The last one is funny. The little guy just went to the dentist and is quite loopy. My son went through the same thing. It only lasts a little while, but it's kinda funny.
