The Twitter thread began with a cheery "Attention, city dwellers!" (you know, that thing normal humans say when addressing other humans) and devolved from there into jokes about "Demogorgon’s" from the TV show "Stranger Things." But it's remarkable that the official request went up late on Aug. 20 — just 10 days before the 5 p.m. EDT deadline on Aug. 30 — for someone to turn over a suitable tunnel complex. (The tweets went up Aug. 28, suggesting that perhaps the agency has not found a suitable tunnel donor yet.)
