#!/bin/env python

import os
import random

text = 'shaks12.txt'
if not os.path.exists(text):
  os.system('wget http://www.gutenberg.org/dirs/etext94/shaks12.txt')

def randline(f):
    for i,j in enumerate(file(f, 'rb')):
        if random.randint(0,i) == i:
            line = j
    return line

print randline(text)
print randline(text)
print randline(text)
