DESCRIPTION:
Ja Rules version from his book

On March 20, I got a call from a friend who happened to be hanging out at the Hit Factory studio in New York City. “Guess who’s in the studio tonight?” she asked. I thanked her for the tip. I knew what I had to do. My man Merc, he had broken his foot. I took his crutch to use as a weapon. I was headed upstairs, because I happened to be at the Hit Factory that night, too. My crew followed me. We paid 50 Cent a visit. He was still talking, rhyming and talking too much shit with his silly mouth. That incident in Atlanta showed me that the beef had just begun. I was getting mad.
Not knowing which studio suite 50 was in, we went from door to door until we found him. I opened the door and 50 was in a small recording studio. He was inches from me. He looked at me like he had seen a ghost.
He said, “Yo, let’s talk.”
“You been talking enough.” BAM! I pushed my way into the studio. I hit him with the crutch. We proceeded to whip his ass. I was putting in my work. 50 was crunched in the corner. I slammed the big Tannoy speaker down on him.
While he’s getting his ass beat, I heard him say, “Get the gun.”
“Get your gun, nigga,” I replied.
At that moment, Black started poking niggas with a knife, and 50 got stabbed. After blood was shed, we got out of there.
