Conspiracy theory of mine - I’m European, so not sure if valid for the other side of the pond, but there was a massive campaign here to recycle the bottle caps by donating them for the creation of incubators for premature births. The local authorities placed massive donation boxes shaped like a heart and they were getting filled constantly.

Here’s the theory: When the campaign started getting up to speed, they started attaching the bottle caps to the bottle, because, I strongly believe, that out there, there is an absolute evil cunt who only feels something when a baby dies, so he wants fewer donated caps, because deep inside he knows people don’t care enough to snap the cap off.
