Grammar in Coen movies.

I just watched Burn After Reading, and it appears the Coens are trying to give their viewers grammar lessons. Several times in the scene where the HardBodies gym custodian gives the CD to Pitt and McDormand, he says, "It was just lying there." And in response to him, Pitt uses the verb "to lie" correctly, too. Reviewers have complained that the movie's premises are unrealistic, but to me what's unrealistic is that CD scene, that correct use of a verb I've heard and read misused thousands of times by talking heads and intelligentsia that should know better.

For the majority of us, the last time we took a grammar lesson was in high school. We could use a refresher or two before the verb "to be" disappears from our language. Movie writers, use the "F" word as you like, but place it in a correctly conjugated sentence. I do!

Thank you, Coen brothers. Please keep it up.
