Is it true that “You shouldn’t put anything smaller than your elbow in your ear”?

Your mother is a smart woman, but there are some things that are completely safe to insert in your ear.

Answer Extra: 

Most of us heard the old elbow bit from our mom, and yes: It is true that using cotton swabs, erasers, pen caps, paper clips or pinky fingers to clean the ears is not safe. But earplugs are designed to protect the sensitive hearing mechanisms while never coming close to touching the ear drum—even when deeply inserted. (But remember: Your mother was right about everything else.)
