I watched TEXAS CHAINSAW 3D (2013) last night. 
It's like jury-duty for fans of the original. 
Anyway, there's a scene where Leatherface (aka "Jeb Sawyer") goes to a carnival and encounters a guy in a pig-mask weilding a chainsaw. 
Was this a MOTEL HELL (1980) reference or just a coincidence? 
Either way, I wish the film had taken advantage of the carny setting and made some inside jokes about Tobe Hooper's THE FUNHOUSE (1981). 
But this movie was not made for me.

Bonus Fun-fact: 
 I was playing a game of TRIVIAL PURSUIT with my wife and the silver-screen category asked:
I was playing a game of TRIVIAL PURSUIT with my wife and the silver-screen category asked: 
What 1980's horror movie includes a climactic chainsaw duel. 
I told my wife: The answer on the card will be "The Texas Chain Saw Massacre Part 2" but the REAL answer is "Motel Hell." 
I was right. You gotta know the limits of the questionnaire.
