Little Johnny's teacher noticed that he was sporting a black eye. She asked him what happened.

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 replied, 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 lay 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."
