OK - hope this translates across the pond.
Frog goes into a bank and goes up to the teller who is wearing a name badge. The frog looks at the badge and sees the teller is called Patricia Wack. He sais "Hello. I,m Kermit Jagger, Mick's son, I would like to borrow 20,000 pounds. Patricia tells him that for that sum of money the bank would need some collateral. He reaches into his pocket and brings out a small jewelled pink elephant and offers it to her. "Will this do?" she takes the elephant and sais "Wait a minute, I'll need to speak to the manager."
Patricia knocks on the managers door and goes in. "Hello Patty, how can I help you?" The manger says.
She replies "There is a frog outside, says his name is Kermit Jagger. He wants a loan for 20,000 pounds he's offering this as collateral." She shows the pink elephant to him and says "what is it?" The manager says
