Olivia Munn and Mr. Feeny in 'Ghost Tits'

"Busty psychological thriller" is not a phrase that gets tossed around a lot in the film world, but that's the best way to explain Ghost Tits, a YouTube parody video staring Olivia Munn and a case of some disappearing boobs.

After her lover gives her an evil purple polka-dot bra, The Newsroom star wakes up in a parallel universe where two of her biggest assets have gone AWOL. Tragically, only her man remembers her former cup size, so in a moment of extreme chest-related crisis, he turns to the only person who can help: Mr. Feeny from Boy Meets World.

Yes, William Daniels shows up in the clip, this time not as your favorite teacher, but as a shrink — obviously Mr. Feeny would never be caught dead saying the word "tits." He's too much of a gentleman.

Watch the clip below — it's full of two things: 1) Shots Olivia Munn giving the evil eye through slowly closing doors. 2) Cleavage.
