JT says a lot of things that are very literal, and very, very funny.
Tonight at bedtime I was trying to adjust the volume on his television. I accidentally hit the tv/video (input) button, switching Spongebob off.
I said, "Oh no, I screwed up!"
From his bed, JT huffed, "NO MOMMY!!! SCREW IT DOWN!!!"
That is, technically, the opposite of screwing it up :)
