How do you get all the perks on Fallout 3

Typically, that's impossible unless you CHEAT. Sorry, I don't know the codes, but you can search them on Google or something. I tried before, just typing in the wrong codes can crash the game and if you type like 20 in a row it'll freeze. So, do a few every ten minutes or so.

See related links for all the perk and quest perk codes which you type inside the console box.
