This movie is so much fun, and pure nonsense. I could only pull one lesson from it;
TELL THE TRUTH! Sooner or later your lies are going to catch up with you and the longer you tell them, the more lies you have to tell to cover up and the more difficult it becomes to remember all the lies.
My Dad always said, "If you always tell the truth, you won't have to worry about not remembering what lies you told." It's funny in a movie, but not so much fun in real life!
