Man, I gotta take a whiz!

So, in order to alleviate the boredom that we endure each day at work, my friend and I decided to give each other challenges. Today, she had to say "dude" at the beginning or end of each and every sentence. Today, I have to drink a full bottle full of water every hour, for twelve hours. I started out fine, but I'm starting to question whether I'll be able to make it. Six or seven trips to the restroom each hour is really starting to cut into my work time.
