As Seen In: Final Destination (2000)
Except for attractive teacher Mrs. Lewton's extravagant sendoff, all of the unprovoked homicides in 2000's Final Destination are relatively quick and basic. For the authority figure's last hurrah, screenwriters Glen Morgan, James Wong, and Jeffrey Reddick hatched a multi-step death that anticipated the increasingly overwrought sequences of later sequels.
Clearly, Mrs. Lewton (Kristen Cloke) isn't a science teacher; her end begins with her lousy decision to pour cold vodka into a hot mug, causing the mug to crack. The vodka steadily drips out, sending droplets into a computer's monitor, the explosion of which lodges a glass shard into Lewton's throat. She stumbles into the kitchen, where the streaming vodka puddle ignites the stove; on the ground after a vodka bottle flies her way, Lewton grabs for a towel but instead knocks a knife holder over. And, yes, she's still alive at this point.
But not for long. Once the stove goes boom, a chair crashes onto the knife lodged in her chest. The lesson here: Coffee mugs are for coffee, not booze.
