Show me a sidehill putt, and I'll show you how gravity has ruined my mouse, drove me to drink, destroyed my marriage, caused me to turn to a life of crime, and worst of all, added strokes to my golf score. Curse you, gravity!
I like how sometimes the gravity of that side hill putt will actually cause the ball to move uphill and then the force of my right arm follow through and force of the mouse hitting the wall with the gravity taking over by depositing the mouse pieces onto the floor resulting with me getting a new mouse out of my bottom desk drawer.
