So... We ALL loved Sesame Street as kids. But,as we aged, parts of the show took on a different context. Bert and Ernie... two male characters who live together. There’s nothing unusual about that to a kid, but as those kids learn more about the world they might start to wonder... Are Bert and Ernie supposed to be lovers? Longtime writer Mark Saltzman says he always interpreted Bert and Ernie as a gay couple when writing them, even if it wasn’t explicit. In Saltzman’s view, Bert and Ernie weren’t just ANY gay couple. In fact, they helped reflect his own relationship to film editor Arnold “Arnie” Glassman, who died in 2003.
