Toilet humour

This morning I remembered a quote from someone with a screechingly funny sense of humour. Her job required her to give very demanding presentations requiring a high degree of mental agility. A screw up would be career changing - and not in a good way. She found these ordeals terrifying and was ritually confined to the bathroom for some time before her appearance. Relating this ritual to me she said, "It's not so much that the bottom is falling out of my world......." (you join the dots up).
