What's a good 5-minute trivia challenge for data scientists?

I got voluntold into hosting this month's team meeting. I'm supposed to prepare a little icebreaker activity for the end of the meeting. Inevitably we always run out of time, but I still gotta have it ready anyway, just in case.

I was thinking of just asking them about random world capitals, because that's something everyone should know more about. But I was wondering if you guys had any better ideas?
