Norman is the assistant to the Grand High Triangle Lover, who appeared sporadically on Sesame Street, beginning in Season 22.

The Grand High Triangle Lover is the expert on all things triangular and often officiates at triangle-related functions or contests. He is always seen with his dim-witted assistant, Norman, who is known for loudly dinging a triangle and telling everyone to make way for his boss. Their chemistry echoes that of Ralph Kramden and Ed Norton on The Honeymooners.
