The Onion's video content is pretty hit and miss. A lot of that has to do with the fact that what works in small, funny blurbs doesn't always translate to sustained comedy that runs for more than two minutes. Their "Who's Fucking" series, however, is pretty genius.
I'm not sure if this is based on something that really exists in the real world or if it's wholly original content, but it's fantastic. If I'm being honest though, as much as I do love to hear about Debra and Josh fucking, hearing from Isaac and Doris is actually even better...
