Michael Lynn Durham (July 10, 1965 – February 16, 2006) was an American professional wrestler, better known by his ring name, Johnny Grunge.

This was not the first time they had met though as The Public Enemy faced one another in Austria c. 1991, with Grunge (using the name "Johnny Rotten") losing to Rock (using the name "Cheetah Kid" and was masked).

[9] The Public Enemy's wrestling style was referenced in Weezer's song "El Scorcho"; the line "watchin' Grunge legdrop New Jack through a press table" was derived from a caption for a photograph of Grunge fighting wrestler New Jack that was published in Pro Wrestling Illustrated.

[14] They then returned to the independent circuit, making appearances with the X Wrestling Federation as The South Philly Posse, where they were managed by Jasmin St. Claire.

He participated in a memorial segment for deceased ECW wrestlers at Hardcore Homecoming on June 10, 2005, and at the end of that year, Grunge was preparing for a comeback.

[16] Grunge died on February 16, 2006, in his residence in Peachtree City, Georgia, as a result of sleep apnea complications, which was most likely caused by a coronary artery blockage due to obesity.
