I never watched MASH as a kid, and in fact hearing the music when the show came on at night prompted me to quickly change the channel.
Then a few months ago I was driving cross country and picked up a TV station broadcasting MASH on the radio. It was a laugh every 20 seconds, I couldn't believe it. After that trip I started collecting the DVDs.
I'm a big fan of Friends, Seinfeld, and other funny sitcoms, but MASH is just hands-down the most hilarious series ever to hit the tube.
The quality of the DVDs are great. I strongly recommend biting the bullet and getting all seasons and watching them from the beginning.
