Look for a loan

A frog is looking for a loan, so he goes into a bank. He sits down at a desk and the name plate says "Patty Whac".

He talks to Patty about the loan and she asks him what he has for collateral. The frog replies well "I have this vase." He pulls the vase out of a bag to show her.

Patty says "well, that's just a cheap knick-knack". Then the owner notices the vase and says to himself, "That's from the 17th century, it's worth tons of money."

So he walks over to patty and says, "That's no knick-knake. Patty Whac give the frog a loan".
