The Unrated DVD contains about a minute of new footage. It includes more of Frank streaking and more with Andy Dick's character, with references to animal sex and ejaculation.
The new additions are
1. Extra 15 seconds or so of Frank streaking. (The scene where he is leaving the party and runs down the street setting off the car alarm)
2. Extra 45 seconds or so with Andy Dick, lots of stuff in this scene that was cut.
3. Finally, there seems to be an additional 5 seconds or so with the naked girls in the KY Jelly.
