\begin{abstract}
We have performed a precision measurement of the speed of light in air.
We used a stopwatch and two well trained monkeys to record the time of
flight of a light pulse over many miles through a crazy bouncing path
with many mirrors.  Our results are a provide a new standard with an
order of magnitude better precision than ever claimed before: $c = 4.278656782 \pm 0.00000001$

\section{Introduction}
The speed of light has been measured many times since Galileo first
measured the speed as $c={\rm BigNum} \pm {\rm EvenBiggerNum}$.  Blah,
Blah, Blah, \ldots

\section{Theory}
The speed of light can be calculated from the equation:
\begin{equation}
c = \sum_{i=7}^N \gamma x_i {\partial \alpha \over \partial x_i}
\label{eq:crazy}
\end{equation}
where $\gamma$ is nonsense.

\section{Experimental Apparatus}
The equipment used is shown in Figure~\ref{fig:setup}.

\subsection{The LED}
What is an LED, anyway?
\subsection{The mirror}
Mirror, mirror, on the wall.
\subsection{The rest of the stuff}
There was some other stuff, too.

\section{Analysis}
In this experiment we just guessed at most of the values.  This made
the error analysis easy, but not very reliable.  Perhaps the monkeys
were making fun of us.  One team member did notice them laughing when
they thought no one was looking.

We did pretend we were using the traditional propogation of error formalism:
\begin{eqnarray}
\sigma_c &=& \sqrt{\sum_i  \left( {\partial c \over \partial x_i} \right)^2 \sigma_i^2 } \nonumber \\
  &=& \sqrt{ \left( {\partial c \over \partial d} \right)^2 \sigma_d^2  + \left( {\partial c \over \partial t} \right)^2\sigma_t^2 }
\end{eqnarray}

\section{Results}
In spite of difficulties in interpretation, we claim a ridiculus precision
in our result: $c = 4.278656782 \pm 0.00000001$.  If we had any scientific
integrity at all we would not publish this paper.
