George has a girlfriend.... however he also decided to have a second girlfriend! The second girlfriend found out that she had been lied and cheated too and wanted revenge! So George was given an ultimatum! Go and visit local spanker Mr X for punishment or she tells his 'real' girlfriend about his sordid affair!
(comment by Ward: George comes across as such an arrogant jerk that by this point in the movie, I really (I mean REALLY) wanted to see him get spanked)
