A frog walks into a bank, and approaches the teller...

He sees the tellers name tag reads Patty Black and says
"I'd like to take out a loan, Ms. Black"

"Certainly," says the teller, "how much would that be for?"

"One million dollars." replies the frog. "Don't worry, it's ok, I know the manager."

The teller is understandably taken aback by this, and asks if the frog has any collateral to cover this.

"As a matter of fact, I do!" says the frog, and he reaches into his pocket and hands over a tiny ceramic elephant.

"What?!" says the teller, "This is garbage! I can't take this!"

"Well, take it up with my father then!" The frog retorts.

"Oh yeah, and who might that be?" The teller is quickly getting more and more annoyed at the frog.

"Why, it's Mick Jagger!" The frog is waiting impatiently, tapping his toe on the ground. "Now, can I have that loan or not?"

"Wait right here" the teller says, as she storms into the back room, looking for her manager.

"There's a frog out there who claims to know you, and wants a million dollar loan. He claims his father his Mick, Jagger! He even gave me this as collateral," she says, holding up the elephant. "I mean, what even is this?"

The manager takes a look at the elephant and replies "It's a knick knack, Patty Black, give the frog a loan. His old man's a rolling stone!"
