Not only can my dog catch, he can pass too

My dog is very clever. 

Since we moved into our new house last march he has invented a new game. He waits at the top of the stairs while i stand at the bottom of the stairs and pass the ball up to him. Then instead of running it down to me, he drops it downs the stairs so it bounces right into my hands. Saves him a trip down the stairs and he loves watching the ball bounce. 

Every time I come up from doing laundry, there's Charlie standing at the top of the stairs with a ball in his mouth, asking me with his puppy dog eyes, "Wanna Play?" 

and I can never refuse.
