"A frog goes into a" joke
A frog goes into a bank and approaches the teller. He can see from her nameplate that her name is Patricia Whack. So he says, "Hello, Patricia Whack. I'd like to get a loan to buy a boat and go on a long vacation."
Patti looks at this frog in disbelief and asks how much he wants to borrow.
The frog says $30,000 and the teller asks him his name, and the frog says it's Kermit Jagger, he's the adopted pet of Mick Jagger and that it's ok, he knows the bank manager.
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 that he can use as collateral. The frog says, "Sure. I have this," and produces a tiny pink porcelain elephant, about an inch tall, bright pink and perfectly formed.
Very confused, Patti explains that she'll have to consult with the manager and leaves the room. She finds the manager and says, "There is a frog called Kermit Jagger out there who claims to know Mick Jagger and wants to borrow $30,000. And he wants to use this as collateral." She holds up the tiny pink elephant and asks, "What the heck is this?"
The bank manager looks her in the eye and says:"It's a knick knack, Patti Whack, give the frog a loan. His old man's a Rolling Stone."
