"couldn't hit a bull on the ass with a banjo"

"... one edifying thought experiment (there are many such) consists of William Tyndale paying a tumultuous visit to Tyndale House, publishers of the inane Left Behind series. One pictures broken windows, crying secretaries, sirens, a major scene, an arrest, and a board meeting the next day with the suits and haircuts trying to decide if they should press charges against this very troubled man. At the end they decide to just make him pay for the damage he did to the sign out front -- the sign that had his name on it. This is an obvious point, but a certain kind of mind still misses it. This is because a certain kind of mind couldn't hit a bull on the ass with a banjo"
