This started as an actual conversation. I often jokingly blame J for feeding me yummy things. I'll eat something naughty (often after he's warned me not to) and then get a hurty tummy. He'll ask "Who's fault was that...?" and I'll point to him as he feigns disbelief at my accusation.
The making of this one went pretty smoothly. J punched up the phrasing in the 1st panel and drew me a funnier "talking while stuffing her face" mouth.
