Every now and then, a sitcom comes along that isn't just forgettable, it's unforgettably bad. We aren't saying we can do better, mind you, we're just saying that it's unbelievable that some comedies progress through multiple stages of development and make it to TV screens while still being irredeemably awful. The latest show to make us shake our heads is The Paul Reiser Show, which is all about Paul Reiser's real life, something that hasn't been very interesting since Mad About You (or even, arguably, My Two Dads). And while there have been bad television shows since the birth of the medium, we're going to focus on the ones that are still freshest (and therefore still painful) in our collective memory. Editor's note: After reading the premise of each of these, insert the words "Hijinks ensue."
