Lamest Office Birthday Celebration ever?

Apparently it got tacked on to the end of a meeting because when I showed up in this fairly small conference room dominated by a huge table, everyone was sitting around still sort of staring at the tiniest writing I've even seen projected on a screen. I was welcomed heartily and grabbed the requisite slice of cake. The organizer of the fun event was yelling out people's names and ascertaining if she had their birth dates, presumably in preparation for future festive events. Having determined she had everyone listed, she promptly left. Uncomfortable silence ensued. Eventually it was determined whose birthday we were actually celebrating. Uncomfortable small talk ensued. People left en masse. The meeting people continued to look dazed at this unwelcome invasion. Good times!
