Grappling - Great Grappling BJJ - At Great Grappling we like to pull pranks from time to time and Halloween is no different. Typically we try to throw parties for the kids whenever we can. It's a way for us to bond as a school and enjoy something other than choking one another.Last month I cooked up this great idea to prank one of my students named Jack. He's a great kid and is always a pleasure to have in class. I just knew the look on his face would be priceless...and I was right!
