A frog goes into a bank and approaches the teller. He can see from the nametag that her name is Patricia Black. So he says, "Hello Ms. Black, I'd like to get a loan to buy a boat and go on a long vacation."
Patti looks at the frog in disbelief, and asks how much he wants to borrow. The frog says "Oh, about $30,000 should do it." The teller asks his name, and the frog says "My name is Kermit Jagger, and it's okay - the bank manager is a friend of mine."
Patti explains that $30,000 is a substantial amount of money, and that he will need to secure some collateral against the loan. She asks if he has anything to use as collateral. "Certainly," Mr. Jagger responds, and he produces a tiny pink porcelain elephant that's about half an inch tall.
Very confused, Ms. Black says that she'll have to consult the bank manager, and disappears into a back office. She finds the manager, and says,
"There's a frog out there by the name of Kermit Jagger, and he claims that he is a friend of yours. He wants to borrow $30,000, and he gave me this as collateral." She holds up the tiny pink elephant. "I mean, what the heck is this?"
The bank manager looks at the elephant, then at her, and says,
"Its a knick knack Patti Black. Give the frog a loan. His old man's a Rolling Stone"
