This may be the creepiest thing to ever happen in the Tanner household. Thanks to the magic of YouTube (and video editing), one YouTuber has created a video erasing Michelle Tanner's very existence from 'Full House.' And it makes the rest of the cast look delusional.

Using clips from the opening credits and the episode 'Working Girl,' the video's description reads, "Did Danny Tanner deal with the grief of losing his pregnant wife in a fatal car crash by creating an imaginary daughter named "Michelle"?" Talk about a conspiracy theory.

If that's the case, then good ol' Tannerito has the entire family in on the delusion. Not only is Michelle absent from the opening credits (the camera cuts to an empty room), but Danny is seen carrying and talking to an invisible person. Stephanie is even sucked into the ruse, having an entire conversation with someone who isn't there. And as the camera pans over an empty chair, the laugh track plays. Super creepy!
