What does a dyslexic, agnostic, insomniac do at night? He stays up wondering if there really is a dog.
It's funny because: This poor afflicted soul's dyslexia has caused him to confuse "God" with "dog." His agnosticism forces him to wrestle with "dog's" existence. And his insomnia has him losing sleep over it.
It's on this list because: You never know someone's struggle.
