Thing To Do Today But Only Of A Thing Of Which You're Actually President: preside.

"Ladies and Gentlemen of the Society of Cake Bakers!

"I address you as President of the Potato Society, and as President I instruct you to stop at once this decadent baking of cakes.

"If cakes are produced then this will reduce the number of potatoes consumed, and this will harm the Potato Society.

"Therefore the baking of cakes is an aggressive act, and I give you warning that if this continues the Potato Society will be obliged to defend itself.

"I speak as President!"
