A specific person you know that you purposely put boxes in front of so they trip and fall over them.
Person 1: Sometimes I place cats and shoes in front of my mom. So, when she gets up to walk, she trips on them. Haha, it's funny, I know, and it's probably not very nice, but she is MY Helen Keller.

Person 2: Haha, Your Helen Keller. How silly. You're a silly Person 1... *smiles*
Get the Your Helen Keller mug.
