A huge muscular guy walked into a martial arts school.
“I’m here to beat up your master!” He bellowed. No one said anything.
He rushed to an old man standing at one corner of the training Hall and proceeded to beat the crap out of the man.
Someone had called the cops. When the cops came the saw the man standing over a broken and bloodied old man, with a few shocked people standing around.
They detained the man and asked, “what happened here?”
Finally someone spoke, “We don’t know. He (pointing to the man) came in and just started beating up the janitor”.
