Best so far is 305 and change.
So this stunning blonde walks into a New York bank and asks to see the loan officer. They're introduced, and she tells him she is leaving on a European vacation and that she needs a loan for $15,000. "Fine," he replies, "Just fill out this application and we'll see what we can do." She does, filling in the Income area with the information that she's an heiress with $30,000,000 in assets and such. The loan officer, perusing the application, says "Great. We will, however, need some form of collateral." My Mercedes is valued at $56,000; will that do?" The blonde replies. "Certainly," says the loan officer, and the deal is done.
Two weeks go by, and the lady returns and pays off the loan and interest, which amounts to $150. "It was a pleasure to do business with you, ma'am," says the loan officer, "but I'm curious. Why would someone with a $30,000,000 fortune need a $15,000 loan, and why would they offer a $56,000 Mercedes as collateral?"
"Simple," quips the blonde, smiling sweetly. "Where else in New York could I park a $56,000 Meredes for two weeks, pay $150, and expect it to be there when I got back?"
