Ted Knight was a voice on the PA in the movie.
Stay tuned for Radar’s butt.
Bravo! 
I respectfully disagree; the teddy bear first appeared in the tenth episode. IHMO, what really did it was a third season episode: “Private Charles Lamb”. You know, the one where Radar got Henry to discharge a lamb.
Without the bear, there wouldn’t be this great exchange in Season Four’s “The Gun”:
Col. Chaffey: Corporal, you’re drunk!
Radar (imitating John Wayne, pointing his bear at the colonel): You better believe it, mister, or I’m dead where you stand!
(gunshot is heard from outside)
Radar: My bear went off!
I recently caught the first “Mail Call” episode, in which Hawkeye says to Frank, “Which war? I’ve been in two.” Of course, he still had Mom & Sis at the time so all this could be attributed to Early Installment Weirdness.
In the EP where Hot Lips got drunk, she says to Hawkeye and Trapper, “Did either of you ever kiss Frank? Frank Burns is a lipless wonder.” And he polished her boots. Maybe not just with polish, if you catch the way I am drifting, which I think is a quote from Henry
I think the first 3 seasons are classic, almost every episode is great, the next two not bad. After that, comedically, not the least bit funny. You can track the shark jumping with BJ’s mustache. For newcomers, if you tune in to an episode, and BJ has a mustache, skip it. Or if Klinger only has an earring. Although, when the stories focused on drama, there were good EPs up to the end
It’s a long time ago, but IIRC at that point Klinger had taken over for Radar as company clerk. He no longer felt like a random victim being acted upon, but was a vital cog in the wheel that saved lives every day. So it was more than just not wanting it on his record. He chose to honorably complete the honorable job he had finally been given.
Actually… 
S2E3, Radar’s Report, was the episode.
And Klinger was still wearing dresses after that episode.
