There were three little boys visiting their grandparents.
The oldest came out and asked his grandpa, "Can you make a sound like a frog, Grandpappy? Grandpa (being in a kind of ill mood) responds, "No, I don't really want to make the sound of a frog now."
So, the second little boy comes out and asks his grandfather, "Will you please make a sound like a frog?" Grandpa again says, "No, not now. I don't really want to do that. I'm in a grumpy mood. Maybe later."
Then the third little boy comes out and says, "Grandpa, oh please... Please, please will you make a sound like a frog?"
"Why do all of you boys want me to make a sound like a frog?" Grandpa asked.
The little boy replied with a hopeful face, "Well, Mom said that when you croak we get to go to Disney World!"
