"That's a pretty big loan for a frog," said Patty.
"Yes it is, but my daddy is Mick Jagger," replyed the frog.
"Well with that kind of loan we would need some kind of security," said Patty.
The Frog quickly reached into his pocket and pulled out a little ceramic duck and handed it to Patty.
Patty stared at it for a second and told the frog that this was highly unusual and she would have to check with her bank manager.
Patty went back to her manager's office confused and explaned that a frog wanted $20,00 for a loan, and he gave her this thing. "What is this thing anyway?"

The Bank manager replyed, "It's a Knick Knack Patty Wack give the frog a loan... his old man's a Rolling Stone."
