Funny Unexpected pop ups

So not too long ago i had a gig; i went in with the expectation of just setting up several breakouts with simple projector and audio support. What actually happened is the op was running late and I had to take over a room with 4 mics, 2 speakers and 2 projectors that was not rung out & 15 min left before show time. I spent my entire shift riding multiple faders to avoid feedback with a board that had the previous show setup from a different group. Had to come back to op again on the same room, so the day before i left, i zeroed the board, rung the room and now its all nicely grouped to a single fader for control. Not complaining, but the situation gave me a good laugh.
