Wanna piss off a chocolate snob?
Tell him /her that your favorite chocolate is "white chocolate."
Faster than you can say, "I know, it's not really chocolate," they'll let you know in uncertain terms that white chocolate isn't chocolate at all.
Then tell them that you don't care cause as far as you're concerned, white chocolate is like vanilla, butter, and Heidi Klum had a threesome.
When you see steam coming out of their ears, tell them you are kidding. And that your favorite chocolate is actually that which is made by Russell Stover.
