Croak

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

"Why sure you can," her grandfather replied.

As she is sitting on grand dad'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."

Perplexed, her grand dad says, "Sweet heart, 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!"
