Just yesterday I read up on some song lyrics that I'd known for over fifty years but never understood.

The song was a Flanders and Swann oldie that is no longer quite PC but in the 50s was sung to mixed audiences on both sides of the pond. The subject was seduction: A roue is trying to talk a young woman into drinking wine with a view to taking her from vertical to horizontal: "Have some Madeira, m'dear."

When she figures out his intent, the actual line is:
"When he asked 'What in heaven-' she made no reply, up her mind, and a dash for the door."

This was what my young ears heard, which my brain did not parse until yesterday the useful internet informed me that this is a zeugma, my mind was supposed to reconstruct from the phrase:

She made no reply
She made up her mind
She made a dash for the door


On the ancient LP, after the song, Flanders tells the audience that Swann's young nephew loves the song, sings it all the time: "He thinks it's about cake!"
