Still an odd choice, not only from the perspective of taste but also from that of practical value. Kennedy died two years before I was born. According to Wikipedia, the median age in the US is about 40 right now.
Kennedy's assassination is declining (has declined?) in a significance as a flashbulb event; today, 9/11 would be a better choice - if we define better based solely on demographic relevance and ignore taste.
Somewhat of a crass introduction that needn't be there. Poor taste for wit.
