One Tree HillGoofs
In the first episode of season 3, it is established that the lockers are in alphabetical order, explaining why Haley is between Nathan and Lucas. In several episodes following, Brooke's locker is shown to be only one locker away from the Scotts' lockers, which would be near impossible with her last name being Davis.
Incorrectly regarded as goofs
Peyton's full name (as seen mentioned many times) is Peyton Elizabeth Sawyer. Peyton says to Haley at one point that Brooke has been calling her "Peyton Marie Sawyer" because of the way she was acting. Peyton then explains that the initials spell PMS revealing that it's just a joke between her and Brooke. Therefore, Peyton's middle name does not change at any time in the series.
