Is there a specifc incident or origin story for the common joke/comedic phrase "my dog ate my homework"? I always wondered whether there was a student who became notorious for not turning in their homework and using that excuse, or whether someone somewhere used it as a flimsy excuse and everyone thought it was funny, or any other reason...
If no one can find anything, do we at least know how long it's been around as a saying?
Also, how often does it turn out to be true? Has anyone here who owned a dog during childhood ever actually had that happen to them?
