The Rat Pack (film) become a big success despite the breakup of his partnership with Jerry Lewis; Sinatra's career is at its peak; Sammy Davis, Jr., is making a comeback after a near fatal car crash, and standup comic Joey Bishop is gaining exposure as an opening act for the other three.

Rat "Rattus". The best-known rat species are the black rat ("Rattus rattus") and the brown rat ("Rattus norvegicus").
