Remember how I talked about the ever addicting, chore-based Rune Factory? Given how much I've played it, K has pretty much memorized all the music, even though he's never touched the game. However, every time my character is watering plants, K completely cracks up at that particular sound effect and starts making, ah, sophomoric motions. To see what I'm talking about, skip to minute 0:30 of the Wii preview for Rune Factory Frontier, the next game in the series. It's not exactly the same, but you get point.
Hehe, the main character also makes funny nom-nom noises at minute 1:15. Silly Japanese developers.
