Local student performs card shuffling marathon
After 17 hours, 17 minutes and 17 seconds, Charles Crutchfield, 1323 Hillcrest, ended a card shuffling marathon he undertook last week. Charlie, who accepted the challenge on a bet with his friends, performed 17 shuffles per hours, 17 one-handed shuffles every hour and 17 stair climbing shuffles during his card campaign. (17 happens to be his lucky number).
Charlie start at 6:42:43 a.m. and went, without break, until midnight. Nourishment was provided via a straw by his friends and his mother. The cast on his leg is the result of a nonrelated injury (basketball) and Charlie suffered only from a sore knuckles.
Representatives from Stancraft Products, a playing card manufacturer, kept him under close scrutiny and a log was kept, which will be sent to the Guinness Book of World Records.
As we figure it, Charlie completed 17,634 shuffles. He is thirteen-years old and a student at Highland Park junior high.
