Sounds like a Sim Instructor after my own Heart!
There were some other "tricks" that could be played that were useful.
In my Sim if you failed to brief the Missed Approach Procedure as part of the Approach Brief.....you could count on the Airport having been kidnapped by Aliens from Outer Space.
During Unusual Attitudes (the old heads down/eyes closed silliness). all I did was turn your Attitude Indicator off about ten degrees in bank.....then made the usual wonky flying thing and then gave the controls back to the pilot.
Three Attitude Indicators and not very many folks polled the Jury and kept fighting for straight ad level. Some never figured it out.
