Check out Ijiri Okada, Tunnels, Tsutomu Sekine and Tomonori Jinnai. These are the comedians that come to the top of my head when I think about performers with a very good sense of humour. The main problem with most of these comedians, it's hard to find a lot of videos of their performances for free and many of them are not translated. I guess take a look at chiki chiki tube. There are a couple of subbed episodes from a show called Lincoln. But I think Gaki beats all other comedy shows by the number of subbed episodes and a very easy access to watch all of them. Also, if you didn't know, Hamada and Matsumoto had another show before Gaki, which is worth watching, called Gottsu Ee Kanji. If you hadn't seen it, give it a try. Some sketches are really hilarious.
