Millennials who grew up watching the Nickelodeon animated series "CatDog" grew up wondering how exactly it was possible for these two animals to be joint together (and particularly how exactly they went about their business), and someone has made a terrible viral video of scientifically accurate "CatDog."

It's not terrible for being bad, but rather how horrible the actual perspective of a scientifically accurate CatDog is, which obviously takes all the cuteness and hilarity of the Nickelodeon cartoon that ran from 1998 until 2005 and was watched by many throughout their childhoods.

You can watch the viral video of scientifically accurate CatDog below, but be warned, it's incredibly creepy!
