Admiral Chu is the leader of the Carcaron military forces. During negotiations with Zapp Brannigan, he was insulted by Brannigan's bumbling attempt to compliment him in his native tongue (instead Brannigan intimates that he'd like to spank Chu's sister with a slice of bologna).
Munda smooths the situation over using her exolingustic skills, but Brannigan later attempts to trick the Carcarons into attacking the Nimbus during his wedding to the newly divorced Munda. When it becomes clear that the Nimbus is outgunned, Munda forces Zapp's hand by making him correctly speak the one Carcaron word that will bring peace. Chu is equally nonchalant at accepting the peace and accepting fishing rights in Super-Nova Scotia.
