This comedy is based on Neil Simon's successful stage play. Alan (Frank Sinatra) is the oldest of two brothers from a Jewish family. When his younger brother decides it's time to leave home, Alan welcomes Buddy (Tony Bill) to his swinging, uptown bachelor pad. Buddy gets a new suit and a lesson on how to be a playboy from his older brother. Buddy soon gets with the program and steals several of Alan's girl friends. His affair with a married woman (Phyllis McGuire) results in a clobbering from her irate husband (Dan Blocker). Alan and Buddy's parents show up to extricate the youngest son from the wicked web of sin. The screenplay comes from Norman Lear, who directed along with Bud Yorkin. Dean Martin makes a comical cameo as a bum, and Sinatra croons the title track. Lear wouldlater make television history with such shows as "All In The Family", the American version of Britain's "Till Death Do Us Part."
