You're trying something that makes you nervous, and for the first half of the week you have no excuse not to really give it your full attention. Impress you-know-who by observing them closely. Then, on thursday and friday, do something that really rattles their expectations. Jumping out of a cake would be a bit too much (not to mention a bit messy! ), but too much is better than not enough. Do something hilarious. Something extreme. Once you've broken the proverbial ice, you can spend the weekend getting to know this person on a deeper level.
