Sixpack Annie (1975)

This likably stupid film should only be watched by people who can turn their brains off, and any intellectual analysis of this film is missing the point. Predictably, the two leads are played by busty women, but these two have a certain charm that is usually lacking in films like this. This movie is also full of silly sexual jokes, but somehow, I actually found many of them to be funny. Perhaps this is because this is a good-natured film, and therefore things never get too raunchy. Whatever the reason, this is a solid viewing selection if you're in the mood for some undemanding fun.
