Whizzer was a clarinetist and band-leader for Whizzer Deaver and the Whizztones, a band that played at Club Juniper on Juniper Street. There are conflicting stories as to how Whizzer and Dorothy met, both mentioned by Dorothy. At first, Dorothy says that she found Whizzer under her sink (fixing it). In the episode, "Break Up to Make Up," Dorothy says that she met Whizzer when he bought her a drink in a jazz club.
