The 41st Ryder Cup will tee off tomorrow at Hazeltine National Golf Club in Chaska, Minnesota but today the golfers from Europe and the United States hit the course for a practice round. 

And the smack talking has already begun.

The man, identified as David Johnson, couldn't wait for his opportunity to step onto the green and show up the pros. Justin Rose even put $100 on it for some added pressure, as if the boisterous crowd wasn't enough.

Here's how it played out.
