SCENE 1 Big Bird greets the viewer, then ambles over to the Fix-It Shop to find out what's going on. Luis, Susan, and Linda are excited about the party Bob is holding. Big Bird thinks he's invited, but Susan explains it's a grown-up party, so he isn't invited. Big Bird is upset and hurt. When Bob arrives, Big Bird confronts him with a spiteful rendition of "Three of These Things" with him and the other adults. When Bob correctly guesses Big Bird's the odd one out, Big Bird storms off in a huff, with Bob trying to catch up and explain. (thetvdb.com)
