656: October 30th
Title text: Not enough houses on your block? Just hit them at 30-year intervals from here to 2300 and get 10x the candy.
For Halloween, a child has dressed up as Dr. Emmett L. Brown (played by Christopher Lloyd) from the Back to the Future film trilogy. In the films, Brown created a time machine out of a DeLorean DMC-12 car, which he and teenage protagonist Marty McFly use to travel through time.
The joke of the comic is that Halloween is on October 31st, and by showing up dressed as Doc Brown on October 30th, the kid can make the joke that he "overshot" the time machine and went back one more day than he meant to. Doc is heard throughout the movie franchise saying "Great Scott" as an exclamation of surprise.
The title text suggests an inventive use of time-travel to get ten times the candy — hitting each house at a 30-year interval up until 2300. The long interval is presumably chosen so you won't need to compete with your older (or younger, if you travel backwards) self in getting the candy. Your neighbours will also be less likely to recognize you. And in 30 years from now, you are probably too old to get candy anyways.
Of course, one would have no idea starting off if Halloween is still being celebrated in 2300, or indeed if the human race even still exists.

- Kid: Great Scott, I must have overshot!
