Tomorrow (September 4th) Hallmark Channel will be airing a Labor Day marathon of uncut M*A*S*H episodes. According to the Hallmark Channel schedule the marathon will start with “Yankee Doodle Doctor” at 1:00PM and end at 3:00AM in the morning with “The Incubator.”
The Hallmark Channel website states that the marathon is of “fan favorites,” but makes no mention of them being uncut episodes. However, a quick search of Yahoo! TV shows that the episodes will be thirty-seven minutes in length, and will not be starting on the half-hour.
Be sure to check your local listings; and there is always a chance the episodes will be the regular syndicated versions and not uncut.
