back in the day when i lived in memphis,tn every year there was a memphis in may festivel and guys would get on stage with 5 gal buckets full of craws like that and see who could get the most out with their mouths. kinda like bobbing for apples lol. guys used to get their faces mangled. gotta love the south! oh and to cook them u gotta get a gas burner with a 30gal pot full of water, sausages,potatoes,corn,and whatever spices you like and boil till red! then throw em on a picnic table and dig in!
