 FACT: When Rob is listing his all time "Most Memorable Break Up List  in Chronological Order", he lists them as 1. Allison Ashmore, 2.  Penny Hardwick, 3. Jackie Alden, 4. Charlie Nicholson, and 5. Sarah  Kendrew. But during the movie, Rob omits Jackie Alden. He later  admits that she wasnt that important after all, and he just slipped  her in to kick Laura out of the top five, though.
