He stayed up all night wondering if there was a dog



wacky, I don't think cartier got this joke either. I mean, he's an insomniac, so he's staying up most nights. Secondly, he's agnostic, so like, he's not sure about the whole god thing. Lastly, he's dyslexic, so when he wonders about god in the middle of the night, he has a tendency to spell the word "god", backwards, spelling it "dog". Hence the funny.
