I used to believe that my grandma took her eyes out every night and put them on the nightstand. In the morning she would put them back in. I was convinced because one morning I asked my mom if I needed to wake up grandma and she told me, ""Oh, she's awake, she's just putting in her eyes."
Apparently that phrase meant glasses.
