pollette seat up?

I see Mr. Churchill has been practising his eye rolls. This is good, albeit limited, exercise, on the order of lifting shot glasses to one's mouth. Myself, I have been practising curling my toes, in case I ever need to perform any of Harry Houdini's tricks on short notice.

I wonder if one ever gets plenty of advance warning that one'll be required to escape from a safe underwater. It'd be handy to know.
