The Friday File: Until recently, the world record for the tallest stack of M&Ms was jointly held by Silvio Sabba of Italy and Brendan Kelbi of Australia. Recently, however, Will Cutbill, a British civil engineer, broke the Guinness World Record. He immediately celebrated his new Guinness World Record by joyously eating his entire gigantic stack of record setting M&Ms, all five of them, yes five! Good luck breaking the record.
