The funnyman has been hosting Le Show on Santa Monica's Kcrw-Fm since 1983, but station executives have now decided to ditch the programme as part of a massive scheduling overhaul.
Bosses hope to continue distributing the programme as a podcast and for national radio syndication, but Shearer is angry he will no longer be heard on the station which launched the show.
He has even appealed for another local station to take him on, writing in series of posts on Twitter.com, "Any radio station in La want to carry Le Show?... Well I guess that's the end of my Kcrw affair."
Shearer goes on to encourage fans of Le Show to express their thoughts to station bosses, adding, "Thjx (thanks) to La Le Show listeners for weighing in on Kcrw decision. If you haven't yet, now's the time."
