This started a few weeks ago. I only found out about it last Sunday. They're in the middle of Season 2 right now. AMC is also airing episodes of M*A*S*H at various times throughout the week. Check out the schedule if you're interested.

I'm watching right now. "Mail Call"from 1974. Includes yet another classic scene of Klinger in Henry's office!!

Henry: "Here's an oldie, but a goodie. Half of the family dieing, other half pregnant". LOL!

I will continue to watch them up to season 5.
