I admit it: I thought this sketch was real when I watched it on YouTube. Thank God for Wikipedia. Apparently, it's from a Flemish television show called "In De Gloria." According to Wikipedia. "In De Gloria was a satire on reality television and human interest programs featuring ordinary people, portrayed by the cast." Man, I need to watch more Flemish comedy.
In this sketch a TV presenter is looking back on the episode that caused him to be fired. The presenter, Eric Hartman (played by Tom Van Dyck), interviews a man whose vocal cords have been damaged during a tonsillectomy so that he sounds as if he's been inhaling helium. The presenter lets out one startled chuckle, then---after an awkward apology---is completely unable to control himself. He laughs and laughs and laughs while the audience stares at him stonily. It's like being inside someone's anxiety nightmare, only funny. Yes, I laughed and laughed and laughed. I felt bad about it, but I laughed anyway. And that's when I thought it was real.
But I wasn't the only one. According to Wikipedia, "The clip is often mistaken for being real, and was showcased on The Tonight Show with Jay Leno and Star Channel news as being so." I'm glad it isn't real. I don't feel so bad about laughing till I fell off the couch now I know I was supposed to. I suppose what Colette said was true: we are each of us innately hostile to our kind.
