In a rice paddy you find a heart and it makes you think. You think a lot of thoughts like, "Whose heart is this? Why is it in a rice paddy? Why am I thinking out loud?"
As you are thinking these thoughts, you spot someone on the edge of the rice field. He really reminds you of someone. But who? That's it! He reminds you of that bartender on The Simpsons. What's his name? You think some more. What is it? Oh! Moe (おも) is his name!
