Grandma Jones from the valley had never experienced a sick day in her life, so she didn't take it kindly when a bad case of the mulligrubs sent her to the hospital for observation.
By the time a pair of husky interns got Grandma tucked into bed, she had managed to complain about everything: the temperature, the lights, the skimpy gown, the food and the mattress, especially, the mattress.
Suddenly, Grandma spotted a small plastic item with a button, attached to a cord. "What's that?" she demanded.
