(The) dog ate my homework

A poor excuse for something that someone has failed to do on time. (From an excuse a student might give for failing to turn in homework on time. Occurs in many variations.) The dog ate my homework, so I have nothing to turn in. (Used as an attributive.) Bob was late with his report and had nothing but his typical dog-ate-my-homework excuses.
