I Dont know whats wrong with this code [on hold]

So I want this code to pick a random item from each list in the order of list1 to list2 to list3. Then I want it to put them into a randomly generated sentence:

from random import randint

list1 = ["Artless", "Bawdy", "Bootless"]

list2 = ["Base-court", "Bat-fowling", "Beetle-headed"]

list3 = ["Apple-john", "Baggage", "Bladder"]

import random

def nurd3(): 
  print (random.choice(list1))

def nurd2():
    print (random.choice(list2))

def nurd1(): 
   print (random.choice(list3))


print ("Thou" + nurd1() + nurd2() + nurd3())
