I actually watched these years ago, they were among the first viral videos I had seen. The best element of these redubbed GI Joe public service announcements are the random and bizarre things Eric Fensler has put in their mouths. “Porkchop sandwiches!”; “I'm a computer.”
Fensler's tidy, great site shows that he's done more than just these incredibly popular spoofs. His work can be seen on spots for Adult Swim's Sealab 2021 and videos for musicians like Daniel Johnston.
