Romance comedies are always fun to watch. There are more than enough hilarious moments that will keep you laughing throughout the movie and a simple plot along with that, that you don't need full attention to follow. Based on the story by Greg Glienna, this movie called A Guy Thing is adapted into a movie and directed by Chris Koch. Paul (Jason Lee) is a nice guy and he is in love with his current fiancé Karen (Selma Blair). He works in her father's company and is really nervous about their wedding that will be held in two weeks. After he had survived meeting with relatives and in-laws, he is to celebrate his bachelor party with his friends. And they know how to make a party. They even invite hot hula girls. As things get out of hand, because of lots of alcohol, Paul finds himself in the bed with one of the hula girls. To make things worse, his fiancé calls to say that she'll be over in couple of minutes and he needs to get this girl out of his apartment. After a few days it turns out that that hula girl is his fiancé’s cousin Becky (Julia Stiles). What will he do now? Will he tell her fiancé what he did? And, what did he do, in the first place? As he doesn't recall anything from that night, he puts all his hopes that he didn't sleep with his future wife's cousin.
