a rather frugal man asked the bank for a loan of one dollar & was told he would have to pay 7% interest at the end of the year. for security he offered $60,000 in U.S.bonds. the banker, seeing a potential depositor, accepted the bonds & gave the man a dollar. at the end of the year, he was back with a dollar & seven cents to clear up his debt & asked for his bonds. upon returning the bonds, the banker asked, "i don't mean to be inquisitive, but since you have all those bonds, why did you need to borrow a dollar"? "well, said the tightfisted old gent, i really didn't have to. but do you know of any other way i could get the use of a safety deposit box for seven cents a year"?
