I'm sure we've all done it, heres the best of my wifes many:

Her first gig of any real size was at The Live Theatre in Newcastle.
She had only been singing professionally for abour 1 month and was invited to do a charity show.
She was support act for a local band and started the show with a 20 min set.
After her last song the audience was yelling out 'more more', when the shouting had died down, she said
"you must all be mad wanting more from me".

Well they were.
The charity was a mental handicap one and half the audience had pieces of paper confirming my wifes statement.
