Another shot at the apple

I heard this one from a good friend while he was teaching.  He told the student, after answering the question incorrectly, “I’ll give you another shot at the apple.”   This is a mash up of  “another shot” and “a second bite at the apple”, both meaning a second try or chance.  My guess is that the speaker, at the moment he said the malaphor, also had a mental picture of William Tell.  Who knows what lurks in the subconscious?
