I am submitting an abstract using a LaTeX template. The template makes use of RevTex 4.1 and it includes an example abstract. In this example, the numbers that show the author affiliation are hard-coded (presumably to show how to deal with the affiliation mess that can arise for more complex author lists):
\documentclass[aps,12pt]{revtex4}
\begin{document}
\title{Why Some Dogs Talk and Others Don't}
\author{\underline{B.~Bunny}$^1$, and
M.~Mouse$^2$}
\affiliation{$^1$Looney Tune Studios}
\affiliation{$^2$Disney Inc.}
\begin{abstract}
...
\end{abstract}
The problem is that this leads to a misplaced "and" between the affiliation descriptions:

How can I modify the code so that this "and" disappears? My author-list actually is quite complex, and I would like to hard-code the numbers as shown here, so that my one-page limit is not blown by the affiliation list.
