Good Excuse

This morning Mark was unable to find a half-finished project he needed to work on at school. He looked high and low and finally went to school without it. Later in the morning I went downstairs and saw Sadie Dog chewing the very "project" in question. Other than being covered in dog drool, the project was undamaged. I emailed Mark's teacher telling him what happened and asking if I should deliver the project to school. In addition to replying that I should take the project to schoool, he said, "This is the first time the 'dog ate my homework' excuse is truly applicable."
