You remember you're pissed off at Ace Dick, and in addition to which, you haven't been able to pee once in the 13 and a half hours you've been locked in your office. You decide to exact revenge by unleashing a torrent of urine through one of the painting holes, preferably while he is spying on you.
Unfortunately, your aim isn't that good, and you don't even come close to getting pee through the holes. The painting is now a smelly mess.
