Hot Tub Time Machine

Ok I will give you one thing the premise of the story is completely ridiculous but it was actually a really good movie.  I mean I love John Cusack he is always so funny especially when he thinks he is loosing his mind.  So the plot of the movie is 4 friends spend the night partying at a ski resort and a crazy illegal caffeinated drink (don't ask) sends them back in time to the 80s.  And they spend the rest of the movie trying to relive the nigh exactly so they don't screw-up the future.  But of course that plan was never going to go well so they spend most of the time screwing everything up in the most hysterical ways.  In the end they get back to the future and their new future is pretty funny as well.  It is pretty explicit so be prepared but I highly recommend the movie.
