A problem with drummers

As a nightclub owner, I hired a pianist and a drummer to entertain my customers. After several performances, I discovered the drummer had walked away with some of my valuables. I notified police, who arrested him.

Desperate for another drummer, I called a friend who knew some musicians. “What happened to the drummer you had?” he asked me.

“I had him arrested,” I replied.

My friend paused for a second and asked, “How badly did he play?”
