Yin has finally thought of a good insult for Carl: He's bugly (because he's a bug and he's ugly). But Carl isn't going to take this insult lying down. He shells out $29.99 for a repulsifier potion from Saranoia and tricks Yin and Yang into drinking it. Now Yin and Yang have turned pug-ugly. Yang doesn't care about how he looks fighting evil, but Yin does and she takes it really hard.
