Give the frog a loan

A frog walks into a bank and says "I wanna loan."


"Well Mr.. frog, go over there to Mrs. Black's desk, she is the loan manager, I'm sure she will be happy to talk to you," The head desk says.


The frog hops over to Mrs. Patty Black's desk and says, "I wanna loan."


Mrs. Black says, "Well Mr. Frog, we will have to get some paperwork for you to sign, so if you will wait right here..." At this point the frog pulls out of his knapsack a golden disk and hands it over to her.


She asks, confused, "What is this?"


The frog croaks back, "I wanna loan." She rubs her head, and walks back to her boss and says, "I don't get it, a frog hops in here wanting a loan, and gives me this golden disk. Do you know what it is?"


The boss laughs and says, "It's a knick-knack Patty Black, give the frog a loan!"
