I remember when I was doing an EA playthrough and I landed a perfect sleep spell. It was a thing of beauty, all failed saves on the enemy, fantastic. Like you just slam your hand against your desk and are like damn.

I then end my turn, and the next turn a couple other enemies start shoving their friends awake and proceed to start slapping my guys around as if my perfect sleep never happened.

It was only slightly less infuriating, though still incredibly infuriating, as watching your companions Benny Hill up and down ladders/climbing on the toilet chain.
