Talk Like a Frog
A 5 year-old girl goes to the hospital with her mother to visit her grandfather. 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, talk like a frog!"
"Well okay dear, but why?" replied her Grandpa.
"Talk like a frog because mommy said that as soon as you croak, we're all going to Disney World!"
