Not Funny

While I was cooking dinner tonight my son said that he had a pain in his leg but when I checked I could not find anything wrong with it and he said he can not see anything either. I told him to take his pants off and put on another pair. While holding his legs I asked him why his skin is lighter than mine I said maybe you are not my son. I told him I was joking but I told him to ask his daddy if I really am his mom. He was so serious he asked his daddy and his daddy told him that he really is my son and that I was only joking with him. I said yes of course I was joking and he was laughing with me and I said that only his daddy knows everything because when I was in the hospital I was asleep.
