Ball On A Tee

I have one of these at my desk. It took me a LOOONGG time to get the ball on the tee. I walk in today and the ball is off the tee. I had this thing in a place that didn't stick out at my desk, so last night someone had to have been playing with it. This upsets me becuase now I have to waste a few hours of time when I am suppose to be working to get the ball back on the tee. I wish it were as easy as getting a ball in a cup.
