Gregory Medavoy is a fictional character (as well as a protagonist) in the television series NYPD Blue. He was played by Gordon Clapp from the third episode of the 1st season to the last episode of the series. Aside from Andy Sipowicz, he was the longest running regular character in the series. Biography Often on the receiving end of jokes about his bumbling speech and mannerisms, Medavoy often provided comic relief. Despite his faults, he was actually a skilled detective who earned respect through his tenacity and inventiveness; he had a knack for talking people into doing things they were initially reluctant to do, including coming to the police station to be questioned, or confessing to a crime. On one occasion, he was commended for bluffing a murder suspect by matching the suspect's rapid fire lies with lies of his own that were so fast and skillful that the suspect believed he had been seen committing the crime, which prompted him to confess. In another incident where he demonstrated his skills and earned a commendation, Medavoy went into a 15th Precinct holding cell undercover and tricked a conman into confessing by pretending to be interested in learning how to execute the con himself. During the series, Medavoy was promoted to Detective Second Grade. The other cops, chiefly Sipowicz, sometimes treated him with contempt due to his tendency to drone on about arcane subjects and his general eagerness to be liked. He was also sidetracked occasionally by thoughts of money making opportunities based on people he met in his police work, including dog breeders, and a conman who sold a book claiming it was possible to legally avoid paying federal income taxes. His partners James Martinez and Baldwin Jones were usually able to get him to focus again with "Let's go, Greg!" or "Come on, Greg!". He was also sometimes the subject of practical jokes, including one where Sipowicz caused him to think free Chinese food he had received from a grateful crime victim whose case he worked on was the subject of an Internal Affairs Bureau investigation, which prompted Medavoy to climb into a dumpster and recover the containers so he could dispose of the "evidence" where IAB detectives would not find it. Initially, he was unhappily married to a nagging woman named Marie, whom he caught cheating on him. He had an affair with Donna Abandando, the squad receptionist,
