the.com/lead balloon
A joke that doesn't fly, because physics agrees it's a disaster.
means An idea, joke, or proposal that fails completely and lands flat, met with silence or disapproval instead of the response you hoped for.
from Straightforward imagery: a balloon is supposed to be light and rise, but lead is one of the heaviest common metals — so a 'lead balloon' can only do one thing, drop like a stone. The phrase took off in the mid-20th century, and it's often credited with inspiring the band name Led Zeppelin, after someone remarked that the group's sound would go over 'like a lead balloon' — a flop that, famously, never happened.
