Michael "Mike" Logan, played by Chris Noth, is a fictional detective in the Law & Order franchise. He has had starring stints on both L&O and its spinoff, Law & Order: Criminal Intent.
In "FOX-y Lady", Det. Logan appeared with his last original series partner, Lennie Briscoe, in an episode of Law and Order. Peter Griffin had been cast as a dead body until he was presumably fired for scratching an itch on his crotch.
