Don't send funny greeting cards on birthdays or at Christmas. Save them for funerals, when their cheery effect is needed.

In this quote, P. J. O'Rourke humorously critiques the use of funny greeting cards for birthdays and Christmas, suggesting that their lighthearted nature is more fitting for times of sorrow, such as funerals. O'Rourke's point is that while these holidays are meant to be joyful and celebratory, the humor often associated with greeting cards can feel misplaced or out of place during significant, emotionally charged moments like birthdays or Christmas. Instead, he proposes that these funny cards should be reserved for more somber occasions, where their cheer can offer some relief and levity.

The quote also reflects O'Rourke's signature satirical and irreverent style, where he often plays with the contradictions of social norms. His comment challenges the conventional expectations of holiday greetings, turning the idea of sending humorous cards on festive occasions into something that feels slightly off-kilter. By suggesting that funny cards are better suited for funerals, O'Rourke is drawing attention to the ways in which society often gets wrapped up in the traditions and expectations of celebrations, perhaps losing sight of what the moment truly calls for.

The quote also hints at the broader theme of emotional appropriateness—that certain emotions and expressions should align with the nature of the event. O'Rourke’s statement makes us question whether humor is always the right choice for a given situation. His humor, though playful, draws attention to the need for a more thoughtful approach when choosing how to express sentiments during special occasions.

Ultimately, P. J. O'Rourke's quote uses irony and humor to make a point about appropriateness in the context of giving cards for holidays. By suggesting that funny cards might be better suited for funerals, he challenges societal norms and forces us to reconsider how we approach the emotional tone of different occasions, encouraging a deeper reflection on how we express our feelings through the rituals of gift-giving and card-sending.
