There are two lessons to be learned from the two new episodes of NBC's Thursday night lineup that aired last night ("My Name is Earl" and "The Office" were repeats):

1) To the makers of "Scrubs:" Editing together a long montage of clips from previous episodes does not qualify as a "new" episode; rather, montage episodes are just "meta-repeats" which are far, far worse and cause much more frustration than mere repeats. For example, I'm not angry with the makers of "The Office" and "My Name is Earl" for their repeat episodes, but I am fuming that the "Scrubs" people tried to convince me they were playing a "new" episode that might actually be worth my time. I mean, seriously, isn't this what YouTube is for? So that some "Scrubs" fan can sit around and compile montages of the greatest moments? Geez.

2) To the makers of "30 Rock": Packing a show with a whole bunch of guest stars does NOT make a good show, it just creates clutter. Yes, I love LL Cool J, Wayne Brady, and even Ghostface Killah, but do we need all three of their star egos crammed into one episode? Spread the love, "30 Rock"! The result was a poorly edited, sparsely written, overwhelmingly muddled episode. Here's a rule for you, "30 Rock" people: tons of guest stars = less Alec Baldwin = bad episode. It's simple math.

I think NBC decided that because their two higher-rated shows in the lineup were repeats that maybe no one else would catch the failures that aired later. Listen up, NBC!  I'm watching, and I'm not happy.
