Bad Guy: Shut the fuck up bitch! You dont got enough money in this purse!
Fat Out Of Shape Karate Guy: I am a black belt in Karate! Stand still so I can hit you and save this woman purse!
Bad Guy: How about I beat you with my boxing skills?
*Bad Guy beats the shit out of Fat Out Of Shape Karate Guy*
Fat Guy: Maybe I should learn a new self-defense, maybe one that works?
Karate is only good against opponents who are untrained. Even then, you still may get knocked out.......
