Lead Balloons
What most people don’t realize is that the phrase “It went over like a lead balloon” is actually a translation from Low Faerie. It’s not quite a perfect translation, though. The original is something more like “NO NO NOT THE LEAD BALLOON ARGGH HE POPPED IT MY EYES MY EYES BURN WITH NOTHINGNESS I CANNOT FEEL MY FACE” and then goes into mumbled bloody spittle as the poison really kicks in.
