Do You Have A Most Useless Talent?

During my daily walk I recently developed my most recent useless talent. I have always wanted to be able to recite the English alphabet backwards so I began during my walks and can now do it quite proficiently. When will I ever use it for a practical purpose? Probably never. Unless, heaven forbid, I get stopped for a DUI (I’m always sure to avoid this situation at all costs). Even so, it is my understanding that any police force doesn’t actually take the method into serious account if they even ask you to recite it at all. That being said, my most recent, perhaps slightly impressive, talent is a vain one. But I’m curious, does anybody else have an impressive and useless talent to share?
