I like the erratic ones. I need to make more of them. They're funny.
Those toilet pranks are annoying though. I've gotten to the point that I discourage my sims from making friends with anybody with that trait, and try to avoid inviting them into their homes.
When my spellcasters go to the magic world, I need to make sure they get their potion skills up fast so they can avoid the need for the toilet, because it seems that the toilets there are ALWAYS pranked!
The really annoying thing is that I can recognize a toilet that has been pranked. They have purple smoke or mist coming out of them. But for some reason, my sims, even super sims can't tell???? Why is it that a high level spellcaster can NOT tell that a toilet has been pranked? Why is it that once you recognize a toilet has been pranked, there is absolutely no way to unprank it, without completely destroying it?
WHY did they stick this in here? Did they just decide that the game was too fun, so they had to add something to the game to ruin it?
