Welcome to the first edition of Don't Do This. Because sometimes we get things hilariously, utterly wrong (according to me, anyway). For example:
Don't do this.
I enjoy the history and battles of the civil war immensely and would never begrudge someone their fascination. However, taking it too far like the lovely couple pictured here just makes you look like an idiot. It's the hobby that screams "I have not had sex in a long, long time". If you must do something like this, keep it in the bedroom (or a room with a door), where it belongs.
