Humor can be a boon to advertising…or the bane of its existence. People have individual tastes, and what one person finds hilarious can be offensive the next. Should you decide to utilize humor in your advertising, keep it light. If you must make fun of something, turn the tables on your own business or product. Poking fun at yourself can bring about the desired response. Poking fun at someone else creates the risk of offending potential clientele.
