In the Sesame Street song, "When Will My Birthday Come?", Grover says that all of his friends are at a birthday party, but he wasn't invited. So he sings a song about having a birthday party of his own, and he wonders when that will be. After he finishes singing, Prairie Dawn comes in and tells Grover that there was a mistake. She thought Farley had invited Grover to the party, and Farley thought that she did, so Grover didn't get invited at all. She tells Grover that everybody wants him there, so they leave for the party.
