When I was in high school, a friend of mine got a water beetle stuck in her ear. She felt something on her ear, and rubbed it... she was asleep so it was a natural reaction. But that caused the bug to go INTO her ear canal. Then it lodged onto her ear drum and she ended up having to have surgery to get the little thing to let go. She had a little bit of hearing loss, temporarily, because of that. Now I am paranoid about bugs near my ears!
