Manzai is a very large part of Japanese comedy in that virtually every comedians start out as part of the "Manzai" duo. Manzai is basically two guys either doing skits, or giving a pre-rehearsed dialogue.
The manzai duo Downtown as I recall, was fresh back then because they didn't follow traditional "manzai" practices; no matched suits, or pre-rehearsed dialogue or I should say they made their dialogues look more "free style."
Here's another one I translated from Downtown. It's not a skit, but them just talking. Manzai style.
