A six year old goes to the hospital with her grandmother to visit her Grandpa.
When they get to the hospital, she runs ahead of her Grandma and bursts into her Grandpa's room... "Grandpa, Grandpa," she says excitedly, "As soon as Grandma comes into the room, make a noise like a frog!"
"What?" said her Grandpa. "Make a noise like a frog because Grandma said that as soon as you croak, we're all going to Disneyland !"
