I just saw a video online that was named “Don’t Tell Mom the Babysitter Fucked Me.”
I think that takes the cake for me so far.
You ever see or hear of any with an equally or more so amusing title?
Forrest Rump…
“Weapons of Ass Destruction” made me laugh. That is, the title made me laugh. I haven’t seen the movie.
Beverly Hills Copulator, starring Traci Lords, no less.
A list of Traci’s films turns up a few gems:
Adventure Of Traci Dick: The Case Of The Missing Stiff
Breaking It: A Story About Virgins
Lust In The Fast Lane
Night Of Loving Dangerously
Tailhouse Rock
Edward Penishands.
I’m torn between *Poke Her Hot Ass * and A Midsummer Night’s Cream.
*Shaving Ryan’s Privates
On Golden Blonde
The Beverly Thrillbillies*
Romancing the Bone
Blow Me Sandwich.
Pulp Friction
Leave It To My Beaver
The Sopornos
Men in black men.
Mr. Blue Sky beat me to it. 
Muffy the Vampire Layer
E.T.: The Extra Testicle
Glad He Ate Her
Rambone
Georgeous Babes Who Wouldn’t Give You the Time of Day in Real Life but You Can Pay Good Money to Watch Them Getting Fucked in a Movie
OK, it’s never been a real porn title, AFAIK, but it should be! 
Likewise:
What “Casting Couch,” Honey? That Was the Part!
I used to work in a video store. How about Sex Trek: the Next Penetration!
Everyone Loves Rimmin’!
Another vote for Edward Penishands
And a call to recognize Schindler’s Fist, even tho it’s just a title used in Orgazmo.
