I'm flying a door

The story:

I was working as a stagehand during a production of Evita, and the
man playing the part of Che was rehearsing this song from the
play. It may have been his enunciation, or it may have been the
acoustics backstage, but at least a few of the other stagehands
heard it the same way.

I don't recall whether one of us looked at the libretto or if one of
the other stagehands already knew the musical, but it didn't take
long before we were all laughing about it.
