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?"
