The 'Get Shit Done' philosophy embraced at most startups, sometimes leads to bad, ugly, stinking code (its not your fault, you din't have enough time :) ).
So what do we do now? We wear our gas masks, grab the refactoring cheat sheet, and get hands down dirty into the shittiest code we have written, and we clean it up. We keep cleaning till it smells of jasmines.
And we come out with battle scars on our faces and a sense of accomplishment in our hearts.
