For the most part, celebrities are an attractive bunch. And when attractive people mate, they usually make cute babies.
But it may turn out that only applies in very specific instances -- and only if celebs are extremely particular in picking the best partner. (Thankfully, Hilary Clinton didn't leave Bill for Steven Tyler.)
For a series in his late night talk show, Conan O'Brien discovered that certain oddball celebrity pairings result in so much hideousness that you will wonder if their DNA had some mutant accident.
Thanks to Imgur user n8w2i who GIF'ed O'Brien's imagining of celeb offspring, we can all be repulsed and equally overjoyed that even famous people genetics can go wrong.
