umpteen zillion years ago I was attending a production of "Don Giovani", back when supertitles were still fairly new (long before the Met put those wonderful seat back screens in...)
After that glorious overture, the curtain rises, Leporello comes out and sings his "Notte e giorno faticar", the translation appears above the action and....
an elderly lady, sitting a few seats to my left and a row or two ahead leans into her husband and says, quite loudly in a craggy, cigarette destroyed LOUD voice (husband was hard of hearing it appears)
"IT SAYS: I'M WORKING NIGHT AND DAY"
The husband replies, (Full voice) "I know this opera, you don't have to do that."
She proceeds to read out loud every title as it comes up...
We left at the first interval.
Of course there was always the matinee of a King Lear done in a small, full thrust theater where a (different) elderly woman was sitting right in the front row, knitting furiously. klick klick klick klick klick... well, you get the idea.
The entire performance would have been a complete wash had not Edmund, during his Act I scene 2 "Thou, nature, art my goddess." soliloquy reach over and grab her knitting, I think it was right after the line "My mind as generous, and my shape as true
As honest madam's issue?"
- he said the line, reached down and grabbed her knitting, said, "These shall be returned to you a nonce" and continued on with the soliloquy, walking over to the wings to toss the stuff to someone offstage.
Needless to say, he not only got the greatest applause during the curtain call, he also returned her knitting and gave her some flowers during his solo bow, which seemed to tickle her no end.
Tragedy most skillfully and artfully avoided.
