A true story:
After a family meal one night, 3 generations of the family are sitting around chatting. A 4 year old is sitting on her grandfather's knee.
4YO: "Grandpa, can you make a noise like a frog?"
4YO: "Can you make a noise like a frog?"
G: "Why do you want me to make a noise like a frog?"
4YO: "Well, last night Daddy said that when you croak we can all go to Disneyland."
Luckily the old man took the comment in good humor.
