Oddly enough, I've never been. Is it worth turning up early for the full tour?
The romper suit is at Chartwell.
I was once wandering around the war rooms when I came upon a room full of shrieking Americans, who had noticed that someone had left a brown paper bag in the corner. Several of them actually pushed past me as they ran out of the room shrieking with fear.
The issue was resolved by my picking up the bag and crumpling it into a ball. The watching Septics, to a man, shít themselves.
