I know, but it wasn't the wrong answer. I put "A coffin" and "coffin", and both times it told me it was the wrong answer. I've heard that riddle before, so I know it's the right answer. Looks like the last time I play on here

Hmm. How about I credit you for the next round. On me. Thats really strange through. The answer was A coffin. if your answer was "A coffin" it would have accepted it. Your answer simply has to be at least 85% similar.
I answered "Coffin," and it was accepted. Almost 100% sure that's exactly how I typed it.
