One of my friends (an American) told me her story:
When she was growing up, she always heard people say:
“See you later, alligator,”
(with the response)
“After a while, crocodile.”
She always thought that It was “See you later, alligator; after a while, crack a dial.” till she was twenty years old.
So “crack a dial” is a mondegreen of “crocodile”.
