There was a classic Victor Borge punch line I will never forget. He could always get the audience in stitches with it. He would play a few bars of his standard-bearer (
Clear the Saloon , aka
Clair de lune) and then he would pause for a moment, as if he was thinking about something. He could time those pauses better than anyone. Then he could begin the story about the two ladies - mother and daughter ("One of them wanted to hear
Clear the Saloon... and the other one didn't.") - and how everyone remarked that these ladies looked very much alike and how remarkable that was - it was hard to tell them apart!
"They both must have looked... very old."
