The Hollywood Sign (as destroyed in The Day After Tomorrow)

City: Los Angeles
Also Destroyed In: 10.5 Apocalypse and Earthquake

That's right, the folks behind The Day After Tomorrow decided that there was no better way to terrify you into recycling and using energy-efficient light bulbs than to show a bunch of letters being destroyed.

Strange Ass Fact: When Hugh Hefner led the initiative to renovate the Hollywood sign in '78, he held a celebrity auction to raise funds, letter by letter. Alice Cooper paid for one of the Os, in honor of Groucho Marx.
