It's not game breaking, but it has a fun quirk that I used to get enough damage to win.

The Tabled Cloth always crits but reduces its damage to 2 (including critical multiplier). By putting a computer on it, it applies a damage boost of +4 after the damage is reduced but before critical multiplier is applied, therefore making it deal 18 damage per hit, very nice.

Then the exercise ball gives me some steady healing. Add in a fridge for some more healing and some more damage, and nice win.
