Last night, I got into bed and was laying there on my back. Before I pulled the sheet over me, I looked down and noticed how my stomach seemed to have disappeared. On further study of this interesting situation, I noticed that my both sides were bulging out a little bit. So, I put a hand on each and pushed in. Low and behold, my stomach popped back out. OK, another of life's little mysteries solved. Now have a great day, you hear?
