I have seen a fair few in my time so here are some of mine
- Dramatic Washing Up. To be done messily and splashily as possible preferably with deep breathing and sighing.
- The Last Biscuit. "No OF COURSE you can have it. It's just a biscuit. I'm fine, fine, fine really I am."
- The Passive Aggressive Bath. Might sound weird but highly effective if the only toilet in the house is in the bathroom. Most effective if you have guest that have just arrived or you are doing it near most people's bed time. Have a long bath and observe the squirming dance/irritation at not being able to do bedtime ablutions.
More effective still if doors are locked and guests have no keys and the kitchen sink isn't an option.
On no account warn your guests about wanting to have a bath.
- Dramatic Housework in general - Particularly if they have it in mind it should be YOUR job. Bonus points if they think that having a penis (or ID'ing as male) absolves you from housework EVER.
