While the boys are in a hotel room, Chad begins to think he is losing his hair. From his lines, the other guys begin to make up the first few words of U+ME=US(Calculus)and the first line of the chorus. Then their manager Bob Buss tells them he booked a gig early the next morning and that they should get some rest. They clearly go to sleep, and then they are shown again at a Spelling Bee. The show goes totally wrong so Jerry leaves without directly speaking to any of his band mates for days. Apparently during this time the song and dance routine was completed without Jerry there.Days later when Jerry returns, he doesn't only know every lyric, but the entire dance routine as well!
