Several of the characters' names are spoofs on the names of Disney staff members. H.U. Hennesy is a spoof on Disney artist Hugh Hennesy, J. Harold King probably refers to director Jack King, and Leslie J. Clark is a play on the name of another Disney artist, Les Clark.
It's possible that this short was inspired by the MGM Cartoons short, Who Killed Who? (1943), as it shares some similarities in addition to differences with it.
