I'm Goin' To Disneyland

A grandson went up to his grandpa and said, 'Grandpa, can you
talk like a frog?'
'No, why?'
'Just wondering.'
A few minutes later the granddaughter came up and said, 'Grandpa,
can you talk like a frog?'
'No. Why do you kids keep asking me if I can talk like a frog?'
'Because Dad said, 'when grandpa croaks, we can go to Disneyland."
