Betsy Butterfly in "Nothing But A Fraud"

At last Joseph Bumble's displeasure passed all control. He began to buzz as loud as he could, hoping to drown Buster Bumblebee's buzzing, so that Buster could no longer talk to Betsy Butterfly.Naturally, Buster soon had to raise his own voice, in order to make himself heard. And soon the two made such a roar that everybody else had to stop up his ears.
Noticing a look of distress on Betsy Butterfly's face, Buster asked her what the trouble was."You and your cousin Joseph are making a terrible racket," she told him.
