standing at the podium of the 10th Annual Symposium on Formal Languages (as per
the banner behind her). <A title=Cueball

crashes in through a glass pane and shouts "GRAMMAR!" and dashes off. <A

at the podium looking perplexed.</DIV>
<DIV>
<P>This is a reference to the phrase <A class=extiw
title="wikipedia:Context-free grammar"
href="http://en.wikipedia.org/wiki/Context-free_grammar">context-free
grammar</A>, which is a technical term used in <A class=extiw
title="wikipedia:formal languages"
href="http://en.wikipedia.org/wiki/formal_languages">formal language</A> theory.
The play on words is that <A title=Cueball

not provide any context for his statement.</P></DIV>

have a feeling it has something to do with context-sensitive grammer (see <A

and formal languages, and possibly that we (the audience) are the
context.<BR><BR>That's my best guess.<BR><BR>-Bobby<BR><BR>
