I’ve heard all the jokes. They’re not funny anymore. It’s not because Cleveland’s sports teams don’t deserve ridicule. It’s because the jokes are too easy. And at some point in the recent past, the knee-slappers turned into something darker. There’s a dagger in those voices now, plunged a little deeper by every TV network that orders its production assistants to whip up a fresh montage showing all of Cleveland’s failures over the last 50 years, in order to play that package in pre-game coverage, during timeouts, and also as part of the post-game show, in case anyone missed it the first dozen times. Sometimes they also include footage of the Cuyahoga River engulfed in flames, just to put a fine point on it.
