One of my guilty pleasures that I do not think I have mentioned is that I love the movie Dirty Dancing (1987). I have this thing with some movies (I am sure I am not alone on this one either) that I can watch them over and over, sometimes back to back, and I never get sick of them. This is definitely one of those.
Another one is Ghostbusters (1984), which is on right now --- thanks to free programming from DIRECTV.
