Croak

A little girl says, "Grandpa, can I sit on your lap?"

"Why, sure you can," her grandfather replied.

As she is sitting on granddad's lap she says, "Grandpa, can you make a sound like a frog?"

"A sound like a frog? Well, sure, Grandpa can make a sound like a frog."

The girl says, "Grandpa, will you please please make a sound like a frog?"

Perplexed, her granddad says, "Sweetheart, why do you want me to make a sound like a frog?"

And the little girl says, "'Cause Grandma said that when you croak, we're going to Florida!"
