Sodor Mail Car w/ factory error - fix or sell?

I dunno.. You might see it a lot on Reddit or Imgur or some very popular forums. I have also seen it being used in chatrooms and text messaging, but not anywhere near as often, since messages are usually much shorter and quicker to post.

EDIT (6:08 PM EST): The acronym dates back to 2003 according to Wikipedia, and it could also be used to refer to the YouTuber TL;DR, who is known for his long political commentaries and satirical discussions, and his channel mascot, which is in fact a deer with teal fur and hair.
