{\bf Now} is {\it the} {\sl time} {\sf for} {\tt all}
{\sc good} persons to come to the aid of their country.

I realize that the {\it original} quotation is now classified
as sexist; would it not have been {\bf better} for the author of this
test document to find a different and more {\sl appropriate} quotation?

$$
\Gamma = {{(A + B) + [a + b] + \gamma / \pi} \over \Pi}
$$
