After a notorious altercation between the two men, Calloway fired Gillespie in late 1941. The incident is recounted by Gillespie and Calloway's band members Milt Hinton and Jonah Jones in Jean Bach's 1997 film, The Spitball Story. Calloway disapproved of Gillespie's mischievous humor and his adventuresome approach to soloing. According to Jones, Calloway referred to it as "Chinese music". During rehearsal, someone in the band threw a spitball. Already in a foul mood, Calloway blamed Gillespie, who refused to take the blame. Gillespie stabbed Calloway in the leg with a knife. Calloway had minor cuts on the thigh and wrist. After the two men were separated, Calloway fired Gillespie. A few days later, Gillespie tried to apologize to Calloway, but he was dismissed.
