Actually, the first Guest is correct in this sense. Allow me to explain.
"Everyday" is an adjective, meaning common, routine, and cannot be used without a subject in the same sentence. However, placing a "the" in front of "everyday" is perfectly acceptable, giving it the meaning of "all that it common."
This comic, however, should have used "Every day" seeing as they were trying to convey the fact that each passing day may not be a good one, but there's something good in each day.
So please, second Guest and all those who upvoted you and downvoted the other, do some basic research before calling anyone other than yourself a moron.
