The L.A. Power Drill Anal Massacre Part IV.
The joke is, there were NO parts I to III.
There’s also

Anal Holocaust
The Anal Disaster Movie**
Mea culpa. Mea summa culpa.
I will state that I didn’t actually watch the movie, I just read the title in my hotel room’s TV cable schedule.
Of course, this has little to do with being a prude (I’m not) and MUCH to do with my not wanting said item to show up on my hotel bill (doubtless to be “shared” with the entire accounting department of my old firm).
Now, there was another business trip when, for some strange reason, the porn channel came in clearly (with sound, but who really cares about the sound?) WITHOUT my having to order it.
Did I watch it? They’re probably still wondering to this day why I pleaded (in vain) to stay at the hotel every time there was a business trip to Chicago! 
There’s a gay porn from the 70’s called HOLE OF THE BRAVE.
