Ohhhh, story time.
I once went to one of these a friend was in (she was Mary, if I remember correctly).
When they went to stab Jesus in the side to confirm he’d died on the cross, the prop retractable spear didn’t retract, and the Jesus actor screamed something along the lines of “Oh, my God, you really stabbed me!” Curtains closed quickly and stabbed-Jesus was replaced by understudy Jesus.
Understudy Jesus was, notably, much shorter.
At the end of the play, Jesus is supposed to ascend into heaven. He did that, but with stage weights set for the first actor… so his ascension was too fast and he screamed in fear.
Then some poor actor in an angel costume had to try and deliver a serious line about “as he departed, so shall he return.”
It was, without a doubt, the most entertaining night of theater I will ever experience.
