Comedy Drama with NO romance (or very little of it)

My brother is wanting to watch a drama with me over the Christmas Holidays, but he wants to watch a show that is funny and has no romance (or very little of it - not the main focus). I think he prefers a drama similar to Kisarazu Cat's Eye (he really loved that one). I tried to show him Hana Kimi in the past, but I think even that had too much romance for him even though I told him it focuses more on comedy (he couldn't even get through the first episode). 

Looking through my PTW list, I was thinking about showing him one of these dramas (but I haven't seen any of them yet). For any of you who have seen them, would any of these be a good choice? Yuusha Yoshihiko to Maou no Shiro -- Nobunaga Concerto -- Kaitou Tantei Yamaneko -- Bitter Blood -- 38 Task Force

Any recommendations would be helpful and it doesn't have to be a Jdrama either! Thanks!

I really enjoyed 38 Task Force! highly recommended ;-)

Avengers Social Club is also a very funny kdrama with no romance

 I recommend Yuusha Yoshihiko to Maou no Shiro! It's really funny. I also second Mr. Nietzsche in the Convenience Store. I haven't finished Kaitou Tantei Yamaneko yet, though I find it funny as well. However, Yoshihiko and Mr. Nietzsche certainly focuses more on the comedy aspect.

I second Yuusha Yoshihiko and Nietzsche-sensei. I'd also like to recommend:

• Aoi Honoo
  
• Tamagawa Kuyakusho of the Dead
  
• Unubore Deka (same screenwriter as Kisarazu Cat's Eye)
  

You can also watch "Tiger & Dragon" it's from the same author of "Kisarazu Cat's eye"

Yuusha Yoshihiko is pretty hilarious like others have said. It might be a bit of an acquired taste.

From the rest of that list Task Force 38 could be a good option. It kind of reminded me of the Oceans 11 move series in some ways though their cons didn't involve quite as much action since it's a Korean TV budget vs. Hollywood blockbuster budget. Con men stealing from bad guys.

Nobunaga Concerto -- Kaitou Tantei Yamaneko  are the 2 i recommend off your watch list.  There is some romance in Concerto but it is SUPER low key and Yamaneko is just fun.
