Which should I play first? Fallout 3 or Fallout: New Vegas?

I bought both (regular FO3 and all DLC pack for FONV, cheap thanks to summer sale)
But which one should I play first? I hear FO3 is good but it's FONV I want to play, but do I need FO3 for context?

@SW-User lol I bought fallout for one character lol

I spent $13 just to get in depth lore on one character and the game's theme for the sake of fanfiction lol.

I know absolutely nothing about fallout aside from apocalypse lol.
It'll be more fun to go into it with hardly any knowledge of what's going to happen. I'm bored of playing games that I'm familiar with in category lol.

It's nothing compared to the thousands of dollars I've probably spent and plan on spending towards tetris lol.
