Contacting the Departed

A woman went to the local psychic in hopes of contacting her dearly departed grandmother. The psychic's eyelids begin fluttering and she begins moaning. Eventually, a voice comes, saying, "Granddaughter? Are you there?" The granddaughter, wide-eyed responds, "Grandma? Is that you?" "Yes granddaughter, it's me." "It's really you, Grandma?" the woman repeats. "Yes, it's really me, granddaughter." The woman pauses a moment, "Grandma, I have just one question for you." "Anything, my child." "When did you learn to speak English?"
