You never know what you'll find while shagging down an errant baseball. Last year, one kid found Nissan's Mr. K. Now, another boy and the Nestle Quik bunny discover a kindly old lady who serves them chocolate milk. In the Quik spot from McCann-Erickson Worldwide, San Francisco, the youngster and the animated rabbit purposely send the ball into the woman's spooky-looking house, which their teammates won't go near because of the "witch" who resides within.
