Sally's final exam
Explanation
Explain Bear
Listen up, buttercup. Sally failed 'cause she didn't write nothin' on her test. It's like showin' up to a gunfight with a banana – utterly useless. You wouldn't know 'bout that though, I heard that you failed your exam too. And probably the ones before, and the ones to come.
