Lol, I'm glad you posted this. I'm almost 100% certain that it was me the OP was playing yesterday because the same exact situation happened when I was playing on my lunch break. This video is where I got the idea for the hook from.
Some of the posts in this thread are a little over the top. It wasn't a money game, so I wasn't bothered too much. I think the OP realized it was just lazy pool playing after he did it. When I pointed it out that it might count as more than just a normal foul in any other setting than a casual game, he seemed to agree. I would have no problems playing the OP again for the record, he was a cool guy.
Great attitude here. However, dropping the cueball onto a cluster is a loss of game. Hopefully the OP has learned that.
