The Mouse That Jack Built

In this spoof of “The Jack Benny Program”, a mouse with Jack Benny’s personality and poor violin playing ability lives, along with a mouse version of Benny’s valet, Rochester, in a hole in a wall of Jack Benny’s own home. Jack the rodent takes a mouse version of Mary Livingstone out to dinner, and the two unwittingly walk right into the disguised mouth of a cat. —IMDb

The cartoon was released on April 4, 1959. Written by Tedd Pierce, it is a parody of “The Jack Benny Program” starring the voices of Jack Benny, Mary Livingstone, Don Wilson and Eddie “Rochester” Anderson as rodent caricatures of their respective radio and television characters, with Mel Blanc reprising his imitation of Benny’s Maxwell automobile (also assuming the voice of “Ed”, Jack’s underground vault guard, usually portrayed on radio and TV by Joseph Kearns). —Wikipedia
