It goes like this...
A teacher in school asks the classroom of children, "Who killed Abraham Lincoln?"
One little child in the front of the room meekly raises his hand, and when called on by the teacher answers,"I didn't do it!"
The teacher is taken aback at the response, and after class calls the child's father and tell him to come in after school to discuss this.
After school, the father shows up and sits down with the teacher, and listens to him repeat the story about what happened in class.
The father is visibly annoyed, and when the teacher is done staunchly says, "If my son says he didn't do it, then he didn't do it!"
Ah, I suppose one could take this as a sad commentary either generally-speaking on the state of our education system or in particular of this family that is quite clueless--and where it's clear that the apple does not fall far from the tree. ;-)
