Yesterday, several of my co-workers the next aisle over decided to pull an April Fool's Joke on one of the managers on that team. They saved the image of the desktop and pasted it into a Power Point slide, and found a way to pause the slide. In that case, the person would come back to her desk and find what she thought was her desktop (since the freeze-frame it looked just like that) and tried to click on things, but, obviously, nothing worked. It was pretty clever.
Also, I tried to create an original recipe last night. I decided to make stuffed tomatoes. I cooked a spaghetti squash and mixed it with broccoli pesto, which I stuffed in tomatoes and baked them, and served with couscous. Problem was, the couscous was just the plain kind (I'd run out of the flavored stuff) so it was kinda boring, and the broccoli pesto had too much lime zest in it. But when I called it lime pesto instead of broccoli pesto, Dan's rating of it went up from an 85 to an 88, largely due to positive associations of lime with Brazil and managing taste expectations. It's all in the positioning.
