Grandpa's Frog Sound

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:

- Willyou 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 whenyou croak we get to go to Disney World!
