Terrific vid, never seen that before either. Very funny.
Rob, I think they aren't confused between the two because of context. Not that it isn't annoying to those that know the difference grammatically. It's just a moot, as opposed to mute point. Folks will use either irregardless of which is actually proper...
I thought irregardless wasn't a word either but spell check corrected me, so I guess it is too now.
