All the blond jokes are "dumb blond" ones, so here's a switch.
A blond babe in New York City walked into her bank to ask for a small loan. She explained to the manager that she was going on a trip to Europe for a month and that she was short in her spending budget by about $1000. The manager said that there shouldn't be a problem, but wondered if she could offer some sort of security.
The blond said that she could leave her Rolls Royce in the bank's private parking lot and pick it up when she returned and repaid the loan. The bank manager agreed and told the blond that the interest on her loan will be 10% and he'll expect her cheque for $1100 when she returns in 30 days. So the blond hands over the keys to the Rolls and leaves with her $1000.
A month later, the blond returns from her vacation and presents the bank manager with a cheque for $1100. The manager gives her the keys to the Rolls, but stops her before she leaves, saying... "If you don't mind my asking, I'm curious and puzzled why you needed to borrow $1000, because we checked your background and discovered that you have thousands of dollars in your bank account, a million dollar stock portfolio, a luxury condo in Manhattan and of course your Rolls Royce".
The blond smiles coyly and says, "Well, where else in Manhattan would I be able to park for a month for $100"?
