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 thats just a cheap knick-knack". Then the owner notices the vase and says to himself "gee that's from the 17th century, it's worth tons of money" So he walks over to patty and says "Thats no knick-knake Patty Whac give the frog a loan".
