[texhax] Weirder and weirder

[Michael Barr]

In connection with the question I raised about revtex a couple days ago, I 
would ask texhaxxers to explain the following behaviour, which has nothing 
to do with revtex.  First, examine the following and try to predict the 
results.  Then run it and see the actual ones.

\documentclass{article}
\showthe\textfont0
\setbox0=\hbox{x}
\showthe\textfont0
\showthe\textfont2
\setbox0=\hbox{$x$}
\showthe\textfont2
\showthe\textfont0
\begin{document}
\end{document}
