"Farewell, Mr. Hooper." While indeed a major Tear Jerker due to the real-life death of Will Lee, let it never be said there weren't heartwarming moments. Big Bird, Maria and Gordon hugging is one such moment. Another is Big Bird's drawing of Mr. Hooper. Unable to give it to his friend like he wanted, Big Bird kept it. It would ultimately be hung over his nest, where it has remained for nearly thirty years. As said on the main page, the loss is handled with honesty, dignity and respect - showing how much both Lee and his character were loved.
In something of a follow-up skit, Big Bird, Maria and David fondly remember him, which puts both the drawing and old footage on display.
During Mr. Hooper's tenure, there was a Running Gag of Big Bird mispronouncing his name - leading to a comically frustrated correction. Caroll Spinney once related a quote from the late Will Lee about why Big Bird was always being corrected:
"He once said to me, 'I will always correct Big Bird because I am proud of being Mr. Hooper.'"
During Christmas Eve on Sesame Street Ernie stumbles upon one of Bert's lost paperclips. He identifies it immediately as a "1957 ACME." Now that's friendship. Ernie doesn't really care about paperclips, but Bert means so much to him that he has actually paid attention and learned enough about paperclips to make that identification.
Again from Christmas Eve, Mr. Hooper has just returned the paperclips and Rubber Duckie. Bert and Ernie are upset that they don't have anything to give Mr. Hooper in return. But Mr. Hooper just smiles. He got to see how much the two cared about each other, and that was a gift to him.
Cookie Monster asks his cousin to find something wonderful that starts with the letter "C." Cousin Monster keeps giving vegetables (corn, califlower, carrot). Then Cookie Monster gives Cousin a one more hint "first class sensational!", and Cousin Monster thinks about it and says "Ohhhhh, Cousin!" and gives Cookie a hug. It's not what Cookie Monster had in mind, but still wonderful. Awwwwwww.
This troper's memory is fuzzy, but that one song where Cookie Monster defines a friend as someone you give your last cookie for.
Brian Jay Jones' biography of Jim Henson begins with a dramatization of filming this scene, making it even better as we get inside Henson's head as he improvises along with the girl right up to "I love you too."
I Love My Hair. A Sesame Street writer adopted a daughter from Ethiopia, and after she told him that she wanted long straight hair like her white Barbie dolls, he wrote the song as a way to show her that she's beautiful just the way she is.
During the '70s, Big Bird's friendship with folk-singer (and recurring guest star) Buffy St. Marie Wolfchild, was genuinely touching. During a period when the other adult cast members insisted that Big Bird's friend Mr. Snuffalupagus was imaginary, Buffy gave Big Bird the benefit of the doubt, because she trusted Big Bird and knew him to be inherently honest.
Following on from that, Mr. Snuffalupagus finally being revealed. Snuffy gets acquainted with the rest of the cast at last, and the adults apologize for not believing Big Bird ("I think you should get that in writing"). The reveal was made primarily to teach children not to be afraid about telling adults serious issues.
In "The Ballad of Casey Macphee" when Cookie Monster was tempted by the chance to eat a bunch of cookies without immediate consequences, but decided to eat the avalanche instead and save the day!
