The FBI in Peace and War - The Collector

Nick Dorso works as a collector for a loan shark named Sylvan Mortinoy. Nick, along with Gus and Arnie, are paying a visit to Mr. Angelo. Nick says "Mr. Mortinoy is a very serious individual. A debt of honor is no laughing matter. What about that huh?" Angelo says "I paid. I paid him already, three time over. Joe Angelo got no money to pay no more!" Nick says "I guess let's have a look at that account sheet. Here we are - Joseph Angelo, 500 dollar loan - Amount still unpaid, 396 dollars. Well, it looks like you and Mr. Mortinoy got different books friend". Angelo says "I paid 500, more than 500 I paid". Nick says "So what about the interest, did you pay that too? Mr. Mortinoy don't take kindly to lending out good dough without loanees paying back with interest". Angelo says "Interest? I pay so much interest!" Nick says "Easy pal, keep your voice down". Angelo says "No, I say what's on my mind! Mortinoy is nothing but a crook! I should've gone to a bank, or a legitimate loan company. I do nothing but pay and pay! There is no end to it! Joseph Angelo does not pay any more!" Nick says "Gus, lock the door and close the transom. Arnie, shut those windows."
