This accident happened on December 21, 2012 – aka the doomsday that failed. Two guys rode a motorcycle down RN-118, a highway in Ipanguaçu, state of Rio Grande do Norte, Brazil and collided with a truck transporting fuel. The impact was so severe, both motorcyclists were practically dismembered – each got some of his limbs severed. Both victims lived in the community of Arapuá in Ipanguaçu.
