Well I vote for the humorous option if it is indeed humorous not just a random word or something. If the option actually makes me laugh then I vote for it. The thing about polls is, I don't take them seriously, half the time I don't even vote, I just answer in my post. If I do vote for the witty option then I will usually still answer in my post. Unless I don't care about the topic.
