There are a lot of areas at home that would be perfect for this kind of prank, and for whatever reason, I woke up today thinking about it. It's probably just too many years of playing Zelda, but really, don't you ever look at a blind corner or lit-up curtain and think "Man, a gigantic spider should be right there!" ......Well, I do. :x And if I had the construction paper to make it, I... probably would. /facepalm.
Anyway, quick comic based on it. Took two hours! That's.... pathetic, but still counts as a good record for me. The panels read downwards.
