The 14-year-old boy in every man is liable to pop out in certain predictable situations -- when someone farts, when the number 69 is involved, and when we hear a vaguely dirty movie title like "G.I. Joe: The Rise of Cobra." (OK, maybe you had to be there for that one.)

Point is, we've got a strong appreciation for movies that don't require any effort to come up with the title of their corresponding porno spoof. Here's a list of some of our favorite movie titles that come with a built-in double entendre, along with how we imagine the flimsy plot line of their adult version might go.

When you're done guffawing, tell us which ones we missed out on by leaving a polite and amusing comment.

"Shaft In Africa"
The seventh sequel to the smash-hit movie about the crime-fighting phallus, "Shaft Goes to Africa" details our hero's adventures spelunking in the bush -- the countryside, we mean.

"The Human Stain"
Eewwwwwwww, we don't even want to know.

"Stick It/Whip It"
A girl is forced to choose between two career paths -- gymnast under the tutelage of a grand master, or a career as a lesbian roller-derby-er. Dirk Diggler stars as the men's roller-derby "jammer" who falls for the rollergirl and "sticks it" all right.

"Doctor T & the Women"
Mr. T stars as Doctor T in this straight-to-the-Internet adult film from 1994. T heads an ensemble cast of ne'er-do-wells and movie stars, all hanging around the office of the finest gyno in Beverly Hills. And boy, do they hang around -- his pity-ful nuts!

"An American Tail"
Two Eurotrash buddies with spray tans and shiny teeth take to the American South in search of a legendary bucktoothed extra from "Deliverance," hoping she'll provide them with some of that famous titular "tail."

"Octopussy"
Octopussy, as you may remember from headlines earlier this year, was the product of a $1 million movie contract drawn up by Vivid Entertainment and given to Nadya Suleman. This made-for-Lifetime movie is notable for being the first television program in history to achieve a 0.0 Nielsen ranking.
