Napoleon Dynamite
This is totally a mormon movie...although it's well hidden.  How many people knew about preston idaho anywho (except us mormons!)  I mean...the Ricks shirt he's wearing (Which is now BYU idaho by the way) is a helpful hint...and plus...the fact that there are no crude words or anything should give it away.  Flippin' and Geez are Heck Yes are famous mormon phrases. WOOT WOOT FOR THE MORMONS!  Also the fact that a young girl is forced to go to a dance with a boy she doesn't like...lol...often occurs in mormon culture. and vica versa...
"Hey Tina you fat lard come eat some dinner" (sorry that was the best part)
"Pedro offers his protection."
"There are much more where these(pictures)came from if you go to the dance with me"
