This is an old one, and maybe you've heard it, but, then again, maybe you'll enjoy anyway ...
A frog goes into a bank and approaches the young lady at the loan desk. He can see from her nameplate that her name is Patricia Whack.
"Miss Whack, I'd like to get a $90,000 loan so I can take a holiday round the world." Pattie looks at the frog in disbelief and asks his name. The frog says "My name is "Kermit Jagger. My dad is is Mick Jagger, and the manager knows him."
Pattie explains that he will need to secure the loan with some collateral. The frog says, "Sure. I have this," and produces a tiny porcelain elephant, half an inch tall - bright pink and perfectly formed. Very confused, Pattie 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 frog called Kermit Jagger out there who claims you know his dad his and he wants to borrow $90,000. He wants to use this as collateral." She holds up the tiny pink elephant. "I mean, what in the world is this?"
The manager replies" Itıs a knicknack Pattie Whack, give the frog a loan. His old manıs a Rolling Stone."
