HAHAHAHHAHAHAH just remembered this.. not me, but a girl in my GCSE Drama class. We were being observed by the examiner, and her group were on stage performing their piece, just before my group went on. She went off stage to get her guitar for a section, someone had knocked it off the ledge and it had completely snapped in two.. she burst into tears, came back on stage without it, and just had to totally skip that part. Then later on, she went to heavily flop onto the sofa on stage, for some reason it didn't take her weight and she fell right through.. everyone on and offstage burst out laughing.. and then to top it all off, as she went to get into her position as a corpse for the final scene, the lights came up, to reveal her clearly not dead and shuffling into position. God love her.. but so funny!
