Last night on Fargo, a man was killed by a postage stamp. Admittedly the stamp was in a glass shrouded frame, and, technically, it was a shard of that glass puncturing the man's jugular vein that caused the death, but still.
This years series includes a sibling rivalry over the stamp that, as indicated, does not go well. Nothing is going well for anyone on the show at this point, except perhaps for the Russian gangsters. Russian gangsters do seem to get their way.
On Seinfeld, some years back, Susan died from licking the backs of too many envelopes, but death by postage stamp is something else entirely.
Also, should one put a valuable stamp "under glass." Seems there would not be enough circulation -- stamps do need to breath. So that part may not have been realistic.
Cheers,
Eric
