We have an 11 month old kitten and, yes, he used to launch himself at us once in awhile. His favorite game was to reach through the stair railing and get us as we walked on the stairs. He doesn't do it very often anymore. I think he's growing out of it. I also heard from somewhere (I wish I could remember) about using a short hissing noise when kittens are being too rough or exhibiting unwanted behavior. If I remember right, it's supposed to mimic the sound the mama cat makes. Whatever, it's worked well for me. Kitty can be in the next room and start scratching on a chair (which he rarely does anymore), I make the "SSST!" noise, and he stops immediately.
