Happy Little Elves
First seen on the Simpsons a ways back, the Happy Little Elves now reside in the hearts of little kids and dreamers. If you don't believe you can do something, just think of the Happy Little Elves and you will believe.
My team sucked, we won one game but then just like the Happy Little Elves, we came back and destroyed our opponents and conquered the universe. We are all heroes!
