Thanks. I didn't know about the historical context of that argument and it turned out to be quite important.

I stand corrected, thank you. I recall being told specifically in 7th grade social studies that that was an actual case in the 1920's where someone did yell fire. I'm aware of other cases where the court decision was, "here's a ridiculous extreme we obviously wouldn't go to, so obviously let's just rule that it doesn't apply at all," and I hate it, so I'll stop using this :)
