Unfortunately, Ned's Declassified was at its all time best at the very end of the series. This episode is one of the all time best in the series, and I would nominate the half-episode - Jealousy- for the funniest 15 minutes of Ned's ever.
The first half "Health" is a very solid half episode with all three leads being afflicted with common puberty problems. This part relies primarily on Cookie's belief that Moze and Ned killed Fayman for its laughs, and it takes a breather from the Moze/Ned/Fayman triangle for a moment.
The 2nd half - Jealousy - is almost non-stop hilarity and spends serious traction on moving the impending Ned/Moze coupling forward. I especially enjoy any episodes with Missy and Evelyn, and they both are serious parts of the action here. Seth is also hilarious and gets some play too. Seth challenges Fayman, hilariously, over Moze's honor, and the two duel throughout the show until they are even more comically joined by Billy. All seem oblivious to the fact that Ned and Moze are pretending to date so that Ned can rid himself of an insanely jealous Missy, who is afraid of Moze. Missy won't easily buy that Ned and Moze are dating, which forces them to get a little closer than they were planning, and of course, making it obvious to everyone else that they SHOULD date. Ultimately, when Missy tries to reclaim Ned, Moze becomes jealous for the first time and takes Ned back, ending Missy and Ned for good. Too bad that Moze's other suitors finally noticed Ned and Moze together. Hahaha...
In a second and equally hilarious plot thread, Cookie creates a fake girlfriend in an attempt to make Lisa jealous. He is unaware that his behavior is making Evelyn jealous at the same time. Thru circumstance, Cookie chooses to claim Evelyn is his girlfriend rather than admit to Lisa that he made the whole thing up. This of course prompts a classic response from both Lisa and Evelyn.
"We're going out? Kiss me, you fool!!"
AWESOME. I've watched many times and it doesn't get old.
