This is sort of funny. This is Matt Damon on the PBS cartoon Arthur. Damon, who has a little daughter, is on the show promoting a feature on the PBS website where kids can send in videos of themselves and PBS will air them. I never watched this show when I was little, but celebrities weren’t do guest appearances on it either. Watch a rip off. If any celebrities ever make any appearances on Eureka’s Castle, let me know.
