<P> Once Bobby returns home he tells Hank what happened, expecting that Hank will stand up for him and talk to Chane's father . However, Hank is not willing to do it this time, instead telling Bobby that he is going to have to learn to fight back and defend himself . In order to do so, Hank comes up with what he believes is the perfect idea and suggests Bobby go to the local YMCA to enroll in a boxing class . </P> <P> Unfortunately for Bobby, when he goes to the Y to sign up for boxing, he finds out the class is full . Bobby asks to be enrolled in something, and is placed into a self - defense class for women because it is the only thing that is open . After some initial reluctance from the instructor, Bobby is allowed to stay in the class and quickly learns and masters the technique taught as self - defense: a hard kick to the testicles, usually preceded by a yell of "that's my purse, I don't know you!" </P> <P> Bobby is able to use this the next day at school, where he once again is accosted by Chane . As Chane is trying to make Bobby eat more dirt, Bobby screams out "let go of my purse", which causes Chane to get off of him in confusion . Bobby then uses his kick, which causes Chane to double over in severe pain . This earns Bobby a reputation around Tom Landry Middle School, and he uses it to push the bullies around, including his rival Clark Peters . However, since he is fighting back and defending himself, Hank and Peggy are overlooking these incidents - which is important, because Bobby is not telling his parents how he is winning the fights . </P> <P> Eventually, the Hills are called into the principal's office for a conference over Bobby's fighting . Hank is still proud of Bobby, but the principal finally makes Bobby tell his parents about his kicking students in their testicles . Hank and Peggy are horrified to hear that bit of information (since groin attacks are considered a taboo amongst young men), and Hank is even more surprised when he hears where Bobby learned that technique from . Bobby is then suspended from school for a couple of days . </P>
