### Keyword Analysis:
- Occasion: Birthday. A celebratory, positive, and personal event happening within a professional context.
- Tone: Funny. The primary goal is humor, wit, and lightheartedness. It requires avoiding anything overly sentimental, formal, or potentially offensive.
- Recipient: Colleague. This is the key constraint. The humor must be "office-safe." It should be relatable to a workplace environment and avoid overly personal, crude, or HR-unfriendly topics. The relationship can range from a close "work spouse" to a teammate you know only professionally.
