I would love to see some of them becoming useful. IE, if you have a fork in your inventory, you can stab an NPC in the eye with it. Comedic effect, really. Nobody with a sense of humor could avoid at laughing while watching an NPC wildly flail around a bar with a fork jammed in their eye.
Maybe even be able to do the magical disappearing pencil trick The Joker used in the latest batman movie?
i hope. i was suprised the bonesaw and frying pan werent weapons
They might have left these weapons out because they don't want to upset Valve. Valve has both as weapons, the Bonesaw being a weapon for the Medic in TF2 and the Frying Pan a weapon in L4D2. Now I don't think Valve is terribly sue-happy, but in this day and age you just can't risk it if you're in the IP business.
Honestly I would have loved a frying pan as a melee weapon. They make the most satisfying 'clang' when they hit something.
