Note to Future Self: Use `ssh -D` to bypass annoying interception proxies

Dear future self,

If you are reading this, you are remembering a time when you ran into a really nasty interception proxy1 and you are looking for a way around it. Do you remember when you were sitting in the Denver International Airport using their free wireless service? And remember how it inserted advertising banners in HTML frames at the top of random web pages as you surfed?
