One day, present-day Madame Foster asked Herriman to sing the song to her, and he accepts. However, Mac and Bloo catch the whole thing and record a video of it, leading to everyone, in and out of Foster's, knowing about the song and finding it funny. Eventually, Mr. Herriman catches sight of the video and becomes enraged and embarrassed, but soon realizes that his fame has led to more people wanting to adopt imaginary friends.
