Actually, my issues with the salesworm (thanks for expanding my vocabulary, dude) were his statements concerning HDTV sets. Technically, he wasn't lying when he said the gov't had ordered all TV broadcasts to be switched to the HD format by such and such date (I think the first gov't deadline has already come and gone, hasn't it?). The implication being: Might as well buy one of these widescreens right now, because in 2006 your current sets will be useless.
I pointed out to him that TV stations make money by connecting advertisers with the populace. As long as the vast majority of people have standard TV sets, that will be the prevailing broadcast signal.
He continued with the BS about how we're all going to have to buy converter boxes for the old sets, blah, blah, blah...
Thus, I believe prevaricating is a more accurate term than lying in this case.
