Motherfuck, he's right. Books, too:
The Discreet Charm of the Bourgeoisie, Motherfucker
On Her Motherfucker's Secret Service
Stephen King's It, Motherfucker
Ghost Dog: The Way of the Motherfucker (wait, it could also be The Motherfucker of the Samurai)
I Am Legend, Motherfucker
Chinatown, Motherfucker (also the film's last line)
Say Anything, Motherfucker (Ione Skye and John Mahoney's relationship would be MUCH different in that version)
Thucydides's The Peloponnesian War, Motherfucker
Band of Motherfuckers
Motherfucker Logan's Run
Mission: Impossible. Motherfucker. (Heck, phrased that way, it suggests a plot...)
Starship Motherfuckers
Motherfucker of the Rings
It's Alive III: Island of the Motherfuckers (I can totally see Larry Cohen doing that. Or Q: The Winged Motherfucker!)
The Iron Motherfucker
The Motherfucker of the Lambs
The King's Motherfucker
Mr. Motherfucker's Opus
Motherfuckers on the Bounty
(I've heard someone suggest that the one title where this wouldn't work would be My Dinner With Andre.)
Any more, y'all? I MUST SHARE THIS.
There. The swearing is done. You're safe. Unless you click on any possible comments...
