A frog went into a bank... He went to the teller's window, her name tag said ""Patricia Whack"". ""Hello Patricia,"" he said, ""I would like a 10,000 loan please."" Patricia was somewhat unsure, and replied ""We will need a guarantor, and some collateral before we could consider that."" The frog said ""That's fine, my father is Mick Jagger, and I have this as collateral."", holding up a small porcelain elephant. Patricia took the elephant, and told the frog that she would have to talk to her manager. She walked into the manager's office and said ""There's a frog outside who says that he wants a 10,000 loan, his dad is Mick Jagger, and he wants to use this,"" showing him the elephant, ""as collateral. What is this anyway?"" Her manager replied ""It's a knick knack, Patty Whack, give the frog a loan - his old man's a rolling stone"".
