Got to your office and think of the biggest bully in the place. Now think of his or her favorite target. Print the bear/rabbit picture, with the caption. Created bubbles with arrows, filled with the appropriate names and attach to the picture.
On second thought, personalities are usually such that this could get you in trouble. But it might work as an inside joke with a friend who shares the same ideas as you, and can be trusted to remain discrete.
This allows the joke to take on a more personal, or secondary meaning.
