A Bird in the Hand Can Play Chicken But Still Smell Fowl! (1x11)

:

With Gasser now a part of his team, Bo-bobo decides to teach him a few things about fighting. The first lesson: how to defeat an opponent without using his own special technique! But when that fails after a battle with a Hair Hunter, his education moves to the "Nosehair Dojo", where beating up fish and fighting old women (and one old man) are on the curriculum.
