Christmas trees are pretty, but they're also dying, amputated prisoners who'd love nothing more than to take out you and your family in fiery blaze. Every year the FDNY tries to warn New Yorkers about the threat posed by Christmas trees, and this time they've released compelling photographs of a Christmas tree going up in flames in a mock apartment. Do not try this at home, at least not inside your home—take it up on the roof, first!

For tips on stopping your Christmas tree from ruining Christmas by burning your house down, check out the FDNY's website. Advice includes using wire or cord to secure your tree to the wall or ceiling, discarding your tree once it becomes dry, turning the tree lights off when its unattended, and NEVER leaving the house with candles burning.
