"A Serious Man" is the movie I think you are referring to. Just looked it up, I wanted to call it "A Simple Man" but didn't want to add further confusion. I loved "A Serious Man"... my son and I constantly make little comments to each other that are lifted from the film. The dad who constantly gets yelled at that others in the house who can't watch "F Troop" (without the dad going to the roof to adjust the antenna) is not really much different from the abuse I get from my family when the Internet in our house goes on the fritz. My one son will start griping about the internet, but his brother will get me smiling with an obscure reference to "F Troop" ("Yeah, dad... Sean needs the internet so he can watch 'F Troop'...") I love the line in the movie where the kid is trying to convince the professor to give him a better grade by offering him a (private) retest but the professor still refuses because its unfair to his other students - and the kid responds "...don't tell anyone, sneaky sneaky hush hush"... "Sneaky sneaky hush hush" is another line that gets repeated often in our house. It's just a fun thing to say - LOL I think the post above that calls the main character a singer/songwriter version of "Willie Loman" is dead on.
