George Clooney is one of the most popular, and famous, actors in the entire world, and yet a number of people are unaware of a rather small part that he has had during his career. Actually, it is a part that you would just not link with him and yet it is right there on his resume.
It turns out that this actor with the smooth voice once played a voice role in the hit cartoon show South Park. Not only that but he played the role of a gay dog by the name of Sparky which is just not the kind of thing that you would generally associate with Clooney. However, it just shows that some actors are willing to try out pretty much anything during their career.
