Got this from my friend Ana E. Muss.
After pulling a ditsy temp secretary off phone duty (she put my phone number instead of the caller's on phone messages), I assigned her to something safe: labeling files.
This task did not include the filing itself, which would have required a thorough grasp of the alphabet; it only involved affixing colorful self-adhesive labels to the outside edge of each file indicating the contract number. She cheerfully labeled throughout the afternoon, completing 150 files.
The next day, my regular secretary asked why our files had been sealed closed with colorful self-adhesive labels.
