Assignment 15: An Impossible Mission.

Declare to one of your friends that you're on a mission.

Any mission will do, be it going to the grocery store, or stopping by the University, or even taking out the trash. Force your friend to scout ahead, and get very upset when he doesn't sing the theme song that you've made up for youselves. Don't forget to give each other spy names, and don't forget to name your mission something innocuous but charming.

When you get home from your mission, jump in the air and shout "Mission Accomplished!" Then treat yourself to chocolate.

Or a maragarita, depending on your age range.
