Stand-up comedians would struggle to find humour in a root canal treatment. Nevertheless, my colleague Trevor Lamb got a mention on stage from one of the UK’s best known stand-ups. The comedian, who must remain nameless, came to see Trevor needing to be got out of pain so he could perform live that very night. Trevor duly delivered and was rewarded with a mention in the comedian’s set later in the day. It’s gratifying to think that thanks to Trevor, who takes his job very seriously, and the very uncomical root canal procedure he performed, many hundreds of people were able to go out for an evening of hilarity.
