sabotage at the maxi pad

i have a Geek Squad magnetic poetry kit on my fridge that i got at Best Buy a long ass time ago. i wrote a poem on it that goes like this:

laptop
i would eradicate
civilians for you

today, however, i noticed someone added a poem. i'm not sure how long it's been there because i never really pay attention. it says:

mission control
deploy the sledgehammer
obliterate computer

what the hell? who did this? speak up, you infidel!
