Where did the deleted scene info come from?

Right now IMDB says "Several scenes were cut from the movie for time. They included: -Mona Lott & Hardbutt 1: 7 minute sex scene between Hardbutt and Mona Lott in the beginning of the movie. -Mona Lott & Hardbutt 2: 6 minute sex scene between Hardbutt and Mona Lott in the middle of the movie. -Mona Lott & Hardbutt 3: 4 minute sex scene between Hardbutt & Mona Lott towards the end of the movie. -Mona Lott & Hardbutt 4: 5 minute sex scene between Hardbutt & Mona Lott after the credits. -A 7 minute sex scene between Nikki and a college guy."

Where is this coming from? Screwballs has the same type of list. It would bring the total time to 106 minutes if added to the 77 minute DVD (not 92).
