I was going to post this myself, but you beat me to it!
It is truly amazing how many people in the world do not know the difference between "Whisky" and "Whiskey"! Of course, the US blurs the distinction, as different whiskies distilled here, use different spellings!
For the misinformed among us:
Scotland, Japan, Canada, (Some) US and others use "Whisky".
Ireland, (Most) US, and others use "Whiskey"
