BBC

“On April 1st, 1957, a BBC news program ended with a three minute segment about a Spaghetti farm in Switzerland. In the segment, spaghetti (not being a popular dish in England at the time) was said to grow on trees. Many people believed the report and called the BBC to ask how to grow their own spaghetti tree. The response: "Place a sprig of spaghetti in a tin of tomato sauce and hope for the best.”
