Is that how it works?

Last night as I put him in bed, my 6 year old son looked at me and asked, "Will I have big muscles tomorrow when I get up?" I was a little puzzled as to where this question came from, so I answered him, "I don't think so, why?" He looked at me, a little disappointed and said, "Because I'm wearing a muscle shirt to bed."

If it only worked that way.....
