Hahah. This used to happen all the time when I was a kid, but to a lesser extent. I had an Australian Shephard so naturally he liked chase down balls and herd things, but he popped any ball that we would get him. Eventually we got him a hard plastic ball, but it didn't look like it was hard. Every time someone new was in the yard they'd try and kick it...and since we are in the US and most people don't know how to kick a ball they would hit right with their toes! OUCH.
