The protagonist is suspected of being a child molester, while his best friend might be homosexual. In any other sitcom made in the early '90s, such a premise would have been greeted with loud boos. But since we're talking about Seinfeld, the insane pitches in question are nothing more than an exquisitely witty start for the celebrated show's third season.
That said, one might wonder how on Earth Jerry might be suspected of something that serious? It's quite simple, actually: he made a few remarks to his physical therapist about a boy who was kidnapped in Pennsylvania, and given the female doctor has a young son of her own she doesn't feel very comfortable around the comedian anymore. As for George, he attempts to get a free massage, only to be taken care of by a man, an event which causes him to question his sexual preferences. Oh, and Kramer claims he saw Joe DiMaggio in a coffee shop.
The Note features some genuinely memorable Seinfeld moments, as always when the script is signed by Larry David. In fact, the whole child kidnapper story arc might have served as inspiration for the bit in Curb Your Enthusiasm where a little girl yells about Larry having "something hard in his pants" (yeah, a bottle of water). The funniest scenes, however, are all George-centric, especially the excruciatingly hilarious scene where he describes the massage he received and says: "I think it moved.". That line, which even got spoofed in Season 4, is George Costanza at his purest: insecure, whining and irresistibly pathetic. Enough said.
