Big Bird brings the number 0 to Hooper's Store to help prove his worth. He orders a banana split from Alan, who discovers he's out of bananas. The zero gets discouraged that he's ruined another situation with his low value, but Alan sings the song show him that the number 0 helps remind him that he needs to order more of something. When he orders some more bananas, he is joined by two singing bananas from the box.
The song parodies "Yes, We Have No Bananas."
