The "Winning Argument" (also known as the Hammer Pipe) is a melee weapon in We Happy Few. It is an extended, longer version of the Lead Pipe with a straight shaft, a t-shaped intersection at the end and a red valve attached to the side.
The Hammer Pipe is a somewhat uncommon weapon, found most easily in Hamlyn Village. It can be randomly found inside lockers, tables, drawers, toolboxes and it is also sometimes wielded by Wellies in combat and can be looted from them. It can also be crafted.
