Michael & Michael Have Issues, the Comedy Central show headed by the titular Misters Showalter and Ian Black, has been canceled, according to a tweet by Showalter. It reads: "To all who were fans of "Michael&MichaelHaveIssues" I can confirm that one week ago Comdy Central cancelled the show. Thanks for watching!" (Yes, he spelled canceled wrong and made the show all one word. He's @mshowalter if you wanna follow him.)
