Mark Wahlberg stole a saucy souvenir from the set of "Boogie Nights" - the 13-inch fake penis he flashed in the 1997 movie.
 
Wahlberg revealed the prosthetic appendage in the famous final scene from Paul Thomas Anderson's porn industry drama.
 
And the actor was determined to keep it as a lasting reminder of his time on the set.
 
Wahlberg reveals, "I used to keep it in my desk drawer. And I'd take it out and slap my friends in the face with it. I don't keep many things from my movies, but that just seemed to have personal significance."
