Regarding destruction: I do not remember details, as I didn't play Sims much, but there was a persistent rumour that by pausing the game at appropriate time - mid-jump into swimming pool by a sim and replacing the target swimming pool tile with a toilet, one could get a Sim to swim in the toilet seat. Another one, which I definitely had seen, involved taking away all doors, then replacing all of the house floor with swimming pool, for obvious end result.
