Classic April Fools Day joke - Panorama - April Fool's Day Hoax - Spaghetti Harvest of 1957

I actually remember seeing this on late night TV as a kid, way back when. It fooled a lot of very stupid people.  From YouTube user aptsarchive:

"On April 1, 1957 the British television programme Panorama broadcast a three-minute segment about a bumper spaghetti harvest in southern Switzerland. The success of the crop was attributed both to an unusually mild winter and to the virtual disappearance of the spaghetti weevil. The audience heard Richard Dimbleby, the shows highly respected anchor, discussing the details of the spaghetti crop as they watched video footage of a Swiss family pulling pasta off spaghetti trees and placing it into baskets. The segment concluded with the assurance that, For those who love this dish, there's nothing like real, home-grown spaghetti.

The Swiss Spaghetti Harvest hoax generated an enormous response. Hundreds of people phoned the BBC wanting to know how they could grow their own spaghetti tree. To this query the BBC diplomatically replied, Place a sprig of spaghetti in a tin of tomato sauce and hope for the best."
