Little Johnny's teacher noticed that he was sporting a black eye. She asked him what happened, and he replied, "Ma'am, you remember I told you how I sleep on the floor next to my parent's bed? Well, last night, my dad asked me if I was still awake, I said yes and then he punched me in the face."
"Ok, Johnny", the teacher said, trying to help, " the next time your dad asks you if you're still awake, don't answer, just lay still and pretend to be asleep."
All went well, until a few weeks later, Little Johnny came to class with another black eye. The teacher asked him why he didn't follow her advice.
Johnny explained, "Ma'am, I tried to, when dad asked me if I was awake, I kept quiet and laid really still, and pretended to be asleep, but then Dad said 'I'm coming', and Mom said 'I'm coming too', and I didn't want them to go anywhere without me, so I shouted, 'Let me just put on my slippers, I'm coming too' and that's when I got punched in the face."
