\section{A proof of some theorem}
In this talk we prove the following theorem.
\begin{theorem}
This is a wonderful scribe indeed!
\end{theorem}
\begin{proof}
Suppose for the sake of contradiction that this scribe is not
wonderful. To put it formally, we write
\begin{equation}
\label{eq:not wonderful}
This\ scribe\neq\ wonderful.
\end{equation}
However, all scribes for this course are wonderful, in conradiction with~\eqref{eq:not wonderful}.
\end{proof}
