You think selling Girl Scout cookies is easy? Well, of course it's easy. They're delicious. But selling more than 21,000 boxes? That's an art.

In this hilarious parody video (created by Mashable), the very real 12-year-old Katie Francis of Oklahoma City reveals her strategy for selling the most cookies in Girl Scout history.

The video starts sweetly enough, as the sixth-grader announces that she recently broke the old record "by selling 21,477 boxes of Girl Scout cookies." Her secret? Play hardball.
