I'm waaaay too tired to write anything. How tired am I? I'll give you a class-participation demonstration. Ready? Ok - first step is to sort of pooch your lips out like you just got a triple dose of botox. Got it? Good. Now, take your index finger and stick it sideways between your lips. Perfect. And for the final step, move your finger up and down and say it with me: "Hbub-badub-badub-badub." That's it! That's how tired I am. Zzzzzzzz.
