I was like, "It's just because you like the poop jokes." And she surprised me, and said "I think some of those are really funny." So, you can blame this comic on my mother-in-law, who loves poop jokes.
But for the real-life scenario that inspired the cartoon, you'll have to blame that on me. Addison sometimes takes a long time on the potty, reading multiple books and singing songs and whatnot. And sometimes she takes a long time to finish her milk, because she's playing with her food or spinning in circles or whatever. So, being the very efficient multi-tasker that I am, the solution seemed pretty obvious.
Although once my wife saw it, the experiment ended. She doesn't respect my brilliance. Or science.
