May is a bittersweet time for television fans. On the one hand, May Sweeps means special events and guest stars galore for your favorite shows -- plenty of fun things to keep you glued to the set even when you really have to go to the bathroom. On the other hand, it's a month for your shows to say goodbye for the summer; sometimes forever.

So much goes on during the Sweeps period, it can be hard to keep track. Luckily, we've got a handy list to help you plan your viewing evenings and coordinate your DVR recordings. After the jump, check out the guest stars, special events, births and deaths you'll be seeing over the next month.

Warning: Spoilers ahead.

The big finales are finally over. Though we have a few cool premieres starting in the coming weeks, from Rescue Me (5/30) to Deadwood (6/11), let's face it -- TV isn't the same after May sweeps. The question that's floated around the TV Squad headquarters in the past couple of months has been, "what else can we review for the readers?" Enter "Retro Squad."

Starting this coming Sunday, we're going to take you back in time just a little bit. Remember all of those great shows that are no longer airing, either from being cancelled or ending long runs and taking a bow? Or maybe you remember the first seasons of shows still on the air? Of course you do; it's what makes you one of the millions of fans of these cult-classic shows. Well, we're going to bring them back to you, one episode at a time, every week. Read on for the exciting details.
