The Sims 2 Cheats

you don't have to make the bed!!!
[1]I'm not really 100% sure this always works but when Alfred[the robot] is in the Penthouse you can sleep in his bed without having to make it!!!

When you get the Rat cave the bed inside the cage doesn't have sheets so you just sleep and never have to worry about cleaning up a mess!!!
