Two Asparaguses.
A boy in Brian's class at school (who he doesn't particularly get along with). They sing the asparagus song, composed by Willie, as a duet for the school play. He appeared in the episode It Isn't Easy Bein' Green. He is quite spoiled, showing off an expensive toy given to him by his seldom-seen father (by way of the father's secretary), and criticizes Brian for making mistakes on the song and getting nervous, Spencer claiming that he is "too good" to work with such amateurs. Spencer ultimately gets his comeuppance when he goes onto the school stage by himself and tries telling jokes, only to be humiliated.
Brian, however, has compassion for him and encourages him to go on stage and perform the asparagus song with him at the Nutrition Follies .
