Sticky Situation

Post-It notes can be a powerful thing.
Step 1: Write on a bunch of sticky notes "When you get a chance please come see me." Then fill in the same name on all the sticky notes.

Step 2: In the morning before people get in, place the notes on varioius coworkers' desks.

Result: What you've just done is set in motion a wave of people that will be looking for your victim to see what he or she wants.

Depending on when they all read the notes, you may get a huge group all at once or they may trickle in one at a time.
