What connects the following?Of course, you’re not looking for just any London theatre, coin, etc., but if you choose the right ones, the connection should be obvious. You should bear in mind that each of the five ‘answers’ is different (see comment by Rob K. below). If you think you have the answer, you can post it in a comment. If you are correct, I will acknowledge that fact immediately, but I will not post your comment until the end of the month, so that later readers can also try to answer the question.
• a London theatre;
• a standard American coin;
• a Roman god;
• a domestic electrical appliance; and
• a police officer.
