Thanks awfully for the cucumber sandwiches my lady but I fear it is now time for draining the moat.

Sorry?

I need to take my corgi for a walk.

Pardon?

It's time to get my valet to lower my trouserings so I may lift my drawbridge and take care of the teathings.

Are you coming on to me?

No my majesty!

Pity.
