Does anyone else's baby constantly throw things?

Since Jaime was about 9 months old, he's been constantly throwing his toys. It's not something he does during a tantrum or to be mean, but he's just having fun. The problem is that he's really started throwing things AT me here recently. Again, he's not trying to be mean, just playing. And telling him "No" is NOT working. I'm starting to get very frustrated every time I am hit in the head with a flying book or something equally as hard/heavy. Has anyone else dealt with throwing? And how did you get baby to finally stop?
