Yep, mine was fromt he movie Jeremiah Johnson with Robert Redford.
Redford charactor, Jeremiah Johnson comes across his friend Del Gue burried up to his neck in dirt in the hot Sun and asks:
"Injuns do this to you?"
Del Gue responds: (In a no-sh$t Sherlock tone)
"Well, it weren't the Mormons"
TPBM has never seen the movie Jeremiah Johnson.
