lol, that's a coincidence, row 4, is the death row, or rather 4 means death in chinese, kinda like friday the 13th' and how there's no 13th floor in most buildings, chinese ppl do not like the number 4.
that along with the tombstone death numbers
and the apple bite jobs face
along with the fact that it's made to fit on the esc key, the "lone" key of the keyboard since it's so separated from every other key
it's really creeper.
