Frog Talk

Young girl gets out of the car and runs into her grandparent's house and jumps into the lap of her granddad. She is SO excited and asks her granddad, "Gramps, can you make a sound like a frog?" He said, "Of course." She was bouncing up and down - VERY excited - "Do it gramps - do it!" The grandfather was perplexed and asked, "Why do you want me to make a sound like a frog?"
The little girl replied, "Cause mama said as soon as you croak, we get to go to Disneyland." :?
