How do you add a flash video to a site?

So if I wanted to add a flash video from http://www.4chan.org/flash/ to my site, how would the script go?

Doesn't work in all browsers. OTOH the shit Adobe suggests isn't valid xhtml, so the "web standards" nutjobs will beat you with printouts of the entire W3C site if you use that. (although try searching for 'flash satay' if you want both; it's a really stupid technique, but it works everywhere and it's standards compliant too.)
