I totally agree. It is definitely the worst movie I have ever seen. When renting it together with a friend, we already feared that this movie might be a bit silly, but maybe funny in a trashy way. It is not. While watching the movie you feel like a 13-year-old boy directed it: The jokes have been borrowed from Police Academy and old Burt Reynolds films (and I like Police Academy!), the story pieces have been "inspired" by mediocre cliche that you have already seen thousands of times and the jokes are simply infantile. Most of the time you see a fat guy tumbling into faeces or you hear Mr. Bones shouting "My prince!". There is a 1-minute dialogue between the "prince" and Mr. Bones that touches slightly pseudo-intelligent ground ("You have to believe in yourself" like stuff) and a ca. 3 minute laughable love story.
To sum it up: The girl falling in love with the prince, plays the role of a subservient woman, the fat guy tumbles into faeces, now and then there are some disgusting jokes regarding animals and Mr. Bones is shouting "My prince!".
