A fish goes into a bank and approaches the teller. He can see from her nameplate that the teller's name is Patricia Whack. So he says,
"Ms. Whack, I'd like to get a loan to buy a boat and go on a long vacation."
Patti looks at the fish in disbelief and asks how much he wants to borrow. The fish says $30,000. The teller asks his name and the fish says that his name is Rainbow Jagger, his dad is Mick Jagger, and that it's okay, 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 he can use as collateral. The fish says,
"Sure, I have this," and produces a tiny porcelain fly rod and reel, about an inch long; detailed and perfectly formed. Very confused, Patti explains that she'll have to consult with the manager and disappears into a back office. She finds the manager and says,
"There's a fish named Rainbow Jagger out there who claims to know you and wants to borrow $30,000. And he wants to use this as collateral." She holds up the tiny rod & reel.
"I mean, what the heck is this??"
The bank manager looks back at her and says:
"It's a knick-knack, Patti Whack. Give the fish a loan. His old man's a Rolling Stone."
