I have never of this film, and after a quick Wikipedia check it seems the poster sums up the whole movie. Almost literally. It is a to each their own world as far as I’m concerned, so if you were looking for a poster of two guys getting it on in a field, here you go.
PS, if this joke offenders you and you need to start of boycott of wtfclassifieds.com, please do. We could use the publicity.
