look up any word, like wcw:
 
1.
Hilariously serious movie that everyone should see. It'll teach you what love really is and isn't. Great ending that isn't ruined by a cheesy "guy-gets-the-girl" scenario, more real life than ever.

...almost as good as the Notebook :)

Starring Joseph Gordon-Levitt and Zooey Deschanel
Did you see 500 Days of Summer? It's such a great movie.

The period of time that the relentless searing heat and suffocating humidity lasts in Houston.
It's Febuary 1st in Houston, time to crank up the A/C, just 500 Days Of Summer left.
