Anyone knows any good wacky grindcore bands that dont take themselves too seriously but still have some sense of musicanship?

Bands like Bathtub Shitter, Gutalax, Jig-Ai, 5 Stabbed 4 Dead and similair? I am not looking for bands trying to be brootal with over-the-top deep vocals and lighting fast drums. I'm more into groove then brutality.

Also, if you haven't, listen to No Stayer cover of Bathtub Shitter, cuz it's just that great ^^
ill Listen to this stuff. I did listen to rompeprop but I was really bored after a while. They didn't suit me :p
