"Guide to: Field Trips, Permission Slips, Signs and Weasels" is the Ned's Declassified School Survival Guide series finale. It is a special episode and two-part TV movie.
The episode starts when Suzie returns at James K. Polk Middle School (in the previous episode), Ned is confused if he really has to be with Moze or Suzie. Jennifer Mosely was in the same situation, because she did not know is she really had to be with Ned. Cookie, on the other hand, was trying to impress Lisa. While the teens were on the trip, Gordy, Coach Dirga, Dr. Wright, Mr. Chopsaw, and the Lunch Lady, wanted to find and capture the Weasel because she destroyed many things that belonged to them.
