Sulky

 
Many people will know that sulky means huffish, sullen or moody.

But did you know that a sulky was a form of one-person horse-drawn light carriage in Victorian times or a low two-wheeled cart sometimes used in harness racing.  I have mentioned a few carriages in the past on this blog but I have just come across a great list for anyone who is interested on a site called phrontistery.
