Well, it's the part where Lord Farquaad is watching the video of Princess Fiona and keeps rewinding it. Well, if you watch closely his pants go up like if he is having an erection, right before that man walks in and he covers himself quickly. Did they put that in there on purpose? Answers please!!
And how exactly is this a slip up? When will people get it that intentional jokes/tidbits, easter eggs, trivia, etc are NOT slip ups? Slip ups are accidents/unintentional mistakes.
