Once upon a time there was a kind elf named Tim who lived in the magical land of Somerville, which should never be confused with the 100-acre-woods or the Shire because Tim does not consort with hobbits or pants-less bears.
Tim would claim to be unpleasant, cantankerous, and pessimistic, but his kindness would shine through whenever he stopped at the nearby apartment of 4 Mormons (Sporty, Geeky, Confused, and Spicy) providing them with home cooked meals and 2 liter bottles of Diet Coke.
He even subjected himself to experimental hair-bleaching without grumbling (see he's smiling).
Then one day Geeky saw a cartoon about Charlie the Unicorn in the magical YouTube window.
When Geeky showed the cartoon to Tim, Spicy, and Sporty, they all started to laugh because Tim is Charlie the Unicorn, except Tim still has both his kidneys and isn't a unicorn.
And that is how Tim the kind elf came to be known as Charlie.
The End
