I remember about a year ago or so I coincidentally watched a TV sketch about a group of people gathering to protest against war. They are shouting "No more war, what is it good for" or something like that. One of the participants stops the protesters and say they shouldn't protest against World War II because they fought against tyranny. So now they are shouting "No more war, what is it good for, except World War II". Each time the single participant stops it and give all the wars an excuse, and at the last scene all the protesters are shouting "KILL KILL KILL".

I do not know what that show's name was, but I surely hope some of you people do. I liked that show, so if there are somebody who can help me, I would appreciate it very much

I think that is from The Sketch Show. Not sure if it was in the British version but it definetly appeared in the American verson with Kelsey Grammer, both of which feature Lee Mack.

That was very helpful, thank you! That sketch is great!

You either learn to live in peace, or rest in it.
