More than 91,000 Facebook users have signed up to a group called “On May 15, 2008, everybody needs to go out and panic buy carrots”.
They plan to go out at 2pm on the designated day and buy as many carrots as they can, reports Sky News.
Student Freya Valentine, who created the original site, insists it is all just a bit of fun.
“We know we’re not going to cause a massive world-wide shortage,” she said.
“To the carroty people who are saying this could never happen – maybe you should be thankful for the imminent rise we are probably going to make it your profits on May 15.”
David Martin, vice-chairman of the British Carrot Growers’ Association, is excited by the idea.
“It’s an extraordinary proposition,” he said.
“Purchasers can be assured they’ll have a fine product in the middle of May – as long as they buy British carrots. Bring it on! Let’s try and reach a million members!”
The 986 members plan to turn panic-bought carrots into soups and other carrot-related dishes, and deliver their produce to the needy and homeless.
