Froggy Grandfather

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