"What is the difference between a hydrocarbon and an alcohol?"
"Hydrocarbons don't cause car crashes."
On a completely different note:
Korean and Japanese are apparantly a "close-surface languages" pair. What does that mean? Swedish and Norwegian weren't taken up as examples, while Hindi - Urdu and Indonesian - Malayan were, so is it about pronounciation? Grammar? Whatever it is, I have yet to find a single word in Korean that is the same as one in Japanese, or even seems vaguely similar. I am admittedly not an expert on either language, far from, but considering I'm studying their most basic words, like "hello" or "cat" or "I am", then... if only the advanced words like, I dunno, "exoskeleton" are the same, I wouldn't call them similar languages. "No" in Japanese means "yes" in Korean, for crying out loud. Maybe it is that they have approximately the same sounds in their language? But so does Swedish - Japanese, right?
