I'm recalling a (years old by now, probably) visual bump with perhaps kaleidoscopic but definitely weird imagery and with cheesy/spoof Slavic accent saying something like:
"We bring you television for happy enjoyment! We hope you find a humorious location to be. The Adult Swim; watches, for you."
I'm sure it's been recorded but my semantic search mojo is... well, I don't have any, apparently. Anyone?
/e: I fear I may've posted this in the wrong subform. Sorry!
You can see it at asfdotcom.net (http://asfdotcom.net/) - in the Download section under Adult Swim General (http://asfdotcom.net/download/as.php), scroll down to "Kaleidoscope Promo"
Thanks, NumyMufn. Those things have a way of nagging at me.
