Frog Knock Knock Jokes

There's this lady who works in a bank...

... her name is Patricia Wack, but all her friends and colleagues call her Pattie. She's very good at her job. One of those people who pays painful and pedantic attention to detail, does everything by the book, and is generally a bit annoying, but does a great job as a bank teller.
One day, while she's going about her daily tasks, a frog hops up onto her counter.
"I want a loan," says the frog.
"Have you filled out the application?" asks Patricia.
"No," replies the frog. "I don't need to bother with all that b**.... Just go and get your manager. I've dealt with him before, and he'll give me the loan."
"Hang on," says Patricia, "I don't see any paperwork or ID, and I don't know the first thing about you. I don't know if you're having me on, or trying to defraud the bank. What's your name?"
"Kermit Jagger," says the frog.
"Now you're really having me on," says Patricia. "Get out of this bank before I call the police."
"No, seriously, go talk to your manager," says the frog. He digs around in his pocket and pulls out a Mr Bean Bobblehead. "Take this and give it to him. He'll know what it is."
Patricia reluctantly takes the toy, and walks upstairs to her manager's office. She knocks on the door, and he waves her in.
"What is it, Pattie?" He asks.
"Well, sir, there's a frog downstairs wanting a loan, but has none of the necessary documents or ID. He says he knows you, and to give you this." With that she places the bobblehead on the manager's desk.
The manager looks at it for a little while, smiles and says, "No worries, Pattie. You can go ahead and approve him up to $20,000."
"But sir!!! He has no ID or credit history with him! He didn't bring any paperwork, and won't do this by the book at all! What's going on, anyway? And what is that... toy that he made me bring to you, anyway?? What's that got to do with it?"
The manager sighs, leans forward, and says, "It's a nick-nack, Pattie Wack. Give the frog a loan. His old man's a Rolling Stone."
