Aah wez once in a folk club where two lady visitors who had 'popped in because we heard the music' were unaware of club protocol and were carrying on a conversation over the singers.

One performer (in between numbers) pointed out the correct behavior to which one lady apologised but the other took umbrage and declared that "If I want to carry on a conversation in public - I Will"

To which the performer replied - "My Goodness! It's You!!! We were all wondering what happened to you and your sister after Cinderella got married"

Another great put-down is "I see you've found the antidote to 'Oil Of Olay/Grecian 2000/etc"
