This answer has a voluntary typo by the author, yet people keep correcting it. I've explained in the edit reason why it should be kept, and it's already been rolled back.
I'm not sure what I should do. On the one hand, the content is community-owned, especially if the edits keep coming (since it'll go in community wiki). On the other hand, I think the author's typo is fun, and the original author should still keep his answer in the tone he wants. (After all, it's not community wiki.)
I don't want to get in an edit war, so I'll just ask here what should be done.
