Cartoon about I think three heroes?

I only remember one of the three "heroes" who wears a viking hat, blonde hair with his eyes hidden, a large chest like Johnny Bravo, he looks like a rock star I think he wears black, they sit on a couch often. The show was aired in Cartoon Network but I can't remember the title. It's more like a comedy show. It is kinda old. Maybe around year 1997 onwards but less than 2007. Thank you!
