Business Bro.

Business Bros. are a type of Hammer Bro whose existence is only implied in Paper Mario: The Thousand-Year Door. The only known Business Bro is Hamma Jamma's father, although there are very likely several more.

Business Bros. seem to be the Hammer Bro answer to the businessman. Therefore, it is assumed that Business Bros. lead a more laid back, controlled, and much less violent life in comparison to normal Hammer Bros. Also, as Hamma Jamma once told Mario, dropping out of Hammer Bros. school to go to Business Bros. school (as his father did) is a responsible (yet, according to him, lame) act.
