There was once a frog (yes a frog) who needed a loan, so he headed over to a bank. Hopping up to a teller he asked if he could get a loan. The teller informed him he'd need to talk to the loan officer, Patty Black. The frog hopped over to her office where she discussed the various principles the bank follows in making loans. She asked him if he had any collateral. The frog didn't understand the concept. The loan officer explained it to him. He reached into his pocket and pulled out a tiny sculpture of an elephant. He asked if that would serve. She didn't know what to make of it, so she explained she'd have to talk with the bank president. She asked the bank president into her office and explained the situation, then held up the sculpture and said she didn't know what it was. The bank president glanced at the sculpture and began to shake his head, when the frog asked if he could have a word in private with him. The loan officer stepped out, and the frog explained that the figurine had a great deal of sentimental and collectable value, as it had been a gift from his father Mick Jagger. "You mean the musician?" asked the bank president. The frog nodded, and the president called the loan officer back into the office. "Well," she asked, "what is that thing?"
"It's a knick nack Patty Black. Give the frog a loan. His old man's a Rolling Stone."
