What am I, a football coach?

Football analogies are really not my thing.  But I'm raising a boy, so I do what I have to do to relate to him.  Today I was nagging him about his lackluster performance in math, and his eyes were glazing over.  Then I said, "You're barely crawling to the 50-yard line, and I know you can make it into the end zone!"  He perked right up and said, "Yeah, Mom, but I got blizted at the ten."
