When she took the back off, I hoped she would notice the anode lead, and the rubber end on it, and say "Look, a suction cup holds this in place. Let me get my fingers under here, and pop it off."
Of course the coating on the tube forms a large capacitor, and the set even once powered off can have thousands of volts. Coming into contact with it, can really give you a real bad "jump start". Perhaps she has done this before... maybe that accounts for the hair style!
