Marathons!

What is it about 4th of July that makes networks air marathons? How can I choose? There's "The First 48" on A&E, "Law & Order" on TNT, and "Wayans Bros." on BET. I'm going with A&E until they show one I've seen and then it's BET. If that's a lame episode, then TNT it is.


P.S. Happy Birthday, America!
