Karate

Hank was a not too smart kind of guy. Everyday when he walked home from work, he would get stopped by three nasty men and they would beat him up and steal his money.
Finally, Hank decided that it would serve his best interest to walk a different route and then take up some self-defense classes so this wouldn't happen again. He joined a karate class and soon was doing very well to defend himself.
So, one day, on the way home from work Hank took his old route home and sure enough there they were. He walked up to them and the battle ensued. The next afternoon Hank went to his karate class with a black eye, a broken nose and a busted lip.
His instructor, shocked, asked him what happened.
"Well," explained Hank, "I took my old way home last night so I could beat these guys up who were stealing my money..."
"Yes," said his instructor, "then what happened?"
"Well, they beat me up before I could get my shoes and socks''
