While checking the tax records, an IRS auditor asked "How did you manage to buy such a luxurious villa while your income is so low?".

"Well," the taxpayer answered, "while fishing last summer I have caught a large golden fish. When I took the fish off hook, the fish made an offer, 'I am a magical fish. Throw me back to the sea and I'll give you the most luxurious villa you have ever seen'. I threw the fish back to the sea, and got the villa."

"How can you prove such an unbelievable story?"

"Well, you can see the villa, can't you?"
