Betelgeuse is rude, crude, and often in a bad mood, so this movie does get a little shocking at times. From the moment we meet the Ghost with the Most, he starts to grope women and complain about his lack of a sex life. His behavior goes downhill from there. He also delivers the movie's major curse word when he yells at Adam, "Nice f***ing model!"
Fun fact: under MPAA guidelines, a movie can use the F-word one time and still get a PG-13 rating.
