I killed it with...
nothing-4
smiling-61
stabbing it with a pen-40
hugging it-37
sticking my tongue out rapidly- 54
moving my head-40
punching-46
moving my computer-25
whistling-62
my cat-62(he started biting my arm-which hurts A LOT-and when there were only a few more hits he bit straight through my hand so I just shook my head and it finished.)
