Bolding mine.
I actually did see a film titled Lord of the G-Strings. Rather amusing.
Some of them do sound oddly familiar… actually I do know for a fact that the previously mentioned:
Edward Penishands
The Madam’s Family
Flesh Gordon
…WERE used as porn titles.
Thanks For The Mammaries
The Lovely Boners
Porn O’Graphy and the Little People
As I read through those, some probably actually exist. I have actually owned or seen
Driller (a porn version of the Thriller video)
Porn of the Dead
Dances With Foxes
The Witches of Breastwyck
Santa Claus Bones the Martians
and some others that are escaping my brain right now.
I cannot confirm or deny that these titles exist in my library.
Though I expect that ‘Cousin Tit’ would be quite a looker. And that Ron Jeremy would do well as Uncle Pester. 
I once saw one called “Fatliners,” in which Ron Jeremy got it on with a morbidly obese woman.

I’ll be damned, there’s actually an IMBD entry for it! :eek:
From the Disney Parody line by Evil Angel…

There were several porn titles mentioned in The Fister King, but “Ordinary Peepholes” is the only one that shows up in the imdb quotes.
The Odd Copulate
Sex and Sexability
Mary Sloppins (it’s not a parrot’s head on the end of her umbrella, if you know what I mean…)
Hannah Does Her Sisters.
The Oh-God Father.
The Sound of Moaning.
Tin D-Cups.
Dances with Pussies.
Bondage of the Willy

This is the only one I ever laughed out loud at the first time I saw it.

You forgot Poke-a-hot-ass.
The Raw Spank Redemption.
The Muppets Do Manhattan
The Great Muppet Orgy

There’s a TV show in Britain called DIY SOS.
And another one called Bargain Hunt. I can’t think what might be made of that.
