I went for a minor procedure at the hospital the other day. As I felt the anaesthetic starting to kick in I said, “I have a joke for you.”
The anaesthetist said, “You’d better be quick!”
I said, “Do you know what the key to comedy is?”
Then I smiled and passed out.
When I woke up a couple of hours later, I asked the nurse to pass the anaesthetist a message: “Timing.”
