Task: Question Answering
Input (English): I would post the rough pencil for this one ... But there is no rough pencil ! I was scraping the cartoon barrel last night , hating all the ideas in my sketchbook . Taunted by my gray , pencil lined mediocrity and a looming deadline , I ducked out to procure some caffeine from the cafeteria , came up with this idea , scooted straight back to my drawing board , took a deep breath , and started inking . Took me about an hour . 
Question: What's a likely reason the writer procured some caffeine ?
Output (English): Because they wanted an energy boost .
