Green-eyed Joe

Convinced that his wife Marilyn Monroe was having an affair, American baseball legend Joe DiMaggio once hired several private detectives to spy on her. One evening, the men learned the Hollywood starlet was planning a rendezvous of some kind.

Intent on catching her in the act, DiMaggio went to the apartment in question and kicked in the door. He was relieved to learn that his wife was not there with another man. He was less relieved to learn that she was in the apartment next door - having dinner with friends.

- envious = wishing you had what another person has
