Leary appeared in sketches on the MTV game show "Remote Control", playing characters such as Keith Richards, co-host Colin Quinn's brother and artist Andy Warhol. He earned fame when he ranted about R.E.M. in an early 1990s MTV sketch. Several other commercials for MTV quickly followed, in which Leary would rant at high speeds about a variety of topics, playing off the then-popular and growing alternative scene. One of these rants served as an introduction to the video for "Shamrocks and Shenanigans (Boom Shalock Lock Boom)" by House of Pain. Leary released two records of his comedy: "No Cure for Cancer" (1993) and "Lock 'n Load" (1997). In late 2004, he released the EP "Merry F#%$in' Christmas", which included a mix of new music, previously unreleased recordings and some tracks from "Lock 'n Load".
