From the Shirtpunch.com's interview with the artist:
"Question: What inspired this design?
Answer: I was walking down the street, reading the 'Cat in the Hat' and some kid was walking in the other direction, watching "the Thing" on his phone. Not paying attention to our surroundings, we collided. "Hey, you got your Seuss on my horror!" "You got your Carpenter on my kids book!" Two great tastes that taste great together."
