The Gap Game

If you haven't tried this game before, I suggest you do. It should be mandatory training for all CIA field officers.

Basically, what you do is enter the Gap and try to touch all four walls, then leave the store, without being approached by a single salesperson. It's extremely challenging, and it usually takes several tries to pull it off successfully. In fact, this game has been attempted in vain so often that most employees at the Gap know about it.
