I'm a Mouse-Potato!

While playing on the computer tonight, Matthew came down to say good-night. He sat down next to me and with a real straight, serious face said "Mommy, you're a mouse-potato." Having never heard this term before, but knowing exactly what it meant, I laughed and asked where he had learned it. Again, with a very serious face, he said "It's an idiom. I learned it in literacy group at school." He cracks me up. I am a mouse-potato!
