Grandma and Grandpa!!!?

Grandma and Grandpa were watching a healing service on TV. The Evangelist called to all who wanted to be healed to go to their TV set, place one hand on the TV and the other hand on the body part where they wanted to be healed. Grandma got up and slowly hobbled to the TV, placed her right hand on the set and her left hand on her arthritic shoulder that was causing her great pain. Then Grandpa got up, went to the TV and placed his right hand on the set and his left hand on his penis. Grandma scowled at him and said, "I guess you just don't get it, do you??!! The purpose of doing this is to heal the sick, NOT to raise the dead!!!"
