Grounding.

My youngest son was talking to his Dad about his school work. He didn't want to do it. His dad told him that if he didn't do it by the deadline, he would be grounded. Youngest son said "I wish I could be grounded from math." His dad said "If you loved math and didn't like video games, we might ground you from math." My son said in a shocked voice "How could anybody not like video games????!!!!"
