You could also tone down the deliberate cuteness. "Hmm what? Oh noes, looks like..." six nothing words before getting to the point: 404. It's wasted space, tediously hip and cloying. I hazard to say most of us older than 12 aren't amused.

I actually find that when a website takes the time to create a personal and interesting 404 page, it signals the fact that they really care about user experiencer. 404 pages can be some of the most jarring things for a user and the fact that they shared some personality and helped the user get back on track says to me that the team is focused on the right things.
