First time I ever drove in England we were out in the country where I thought I would be safe. We came up to one of those really tiny roundabouts that exist out there, I got so confused as to which way to turn I drove straight over the top of it in this little ford we had rented. The wife was at first silent but then turned to me and said "we generally drive round them not over them" that was it.
I saw a list of Cricket Rules in a pub once, they lost me at "when you are out you are in" . I believe Cricket was invented as a way to confuse the rest of the world.
