I actually find this headline pretty funny considering the grim details:
The ‘slice’ coming from:
Each had been charged with attempted murder after carving each other up in a knife fight — reportedly over a woman — on Smith Street in Carroll Gardens
The story has a mob angle, a knife fight, a ‘love’ triangle, pizza and uncooperative witnesses! The writers of the television show, Castle, probably could have dreamed this one up (although, they actually did have a pizza-themed episode titled ‘Slice of Death‘).
