A frog enters the bank to get a loan. He approaches the woman at the loan application desk and notes that her name tag reads: Patty Whack.
The frog says, "Excuse me, my name is Kermit Jagger. I'd like to apply for a loan."
The woman says, "Okay, we might be able to help you with that... if you have something of value to secure the loan with."
"Why, yes, of course!" replies Kermit, handing Patty a small pink ceramic elephant.
Confused, she says, "I'm not sure we can accept this as collateral..."
The frog replies, "Well, please speak to the manager about it. He and my dad are friends."
She does so, and asks the manager, "Sir, there is a frog outside trying to get a loan from us. He says his name is Kermit Jagger, and believes that this weird pink elephant thing will suffice as collateral. What is it anyways?"
The manager looks at the figurine and explains, "It's a knick knack, Patty-Whack. Give the frog a loan. His old man is a Rolling Stone."
