I hate to be that annoying guy and say "I told you so", but..... I have been saying for almost a year that Mad Men is the best show on television. If you haven't heard, Mad Men is up for something like 16 Emmy nominations. This is an amazing accomplishment for a show on the AMC network. It's back for season two tonight at 9pm.
My advice is to watch season one. It's only 13 episodes. They are for sale on DVD, you can get them on demand from Time Warner or you can get them from itunes. Watch this show! I love it, love it, love it.
