I forgot to feed my cat. So she splattered poop all over DVDs for Its Always Sunny In Philadelphia (season 6), Grand Theft Auto: San Andreas, and my Robbin' The Hood CD by Sublime. TT^TT Those are like, the only things I ever use.
Having to help a customer with 69 different stapled documents and having to remove the staples, copying them and then stapling them back back together.... Major fuckage there...
