-50 HP, +1 Snobby
I drop a gargantuchicken. Which is a considerable effort on my part, on account of the gargantuchicken weighing in at 500 pounds, and being taller than twelve copies of me standing on top of each other. It has one million HP and you can only deal 1000 damage to it at a time.
I'm amazed that I carried that around in my back pocket all these years.
