I'm a non-dyslexic atheist who has insomnia, so I had to look up the answer for this riddle.

A person who stays up all night wondering if there is a dog.

Ok thanks. I am curious if someone from another country can figure out or even understand it when I or someone writes the answer.

I think I know the punch line to your joke, but I won't give it away.

On a more serious note, I am a charter member of DAP, People Against Dyslexia.
