Give the group 3 minutes (or a number in some relation to 3) to find 3 different people and ask them 3 questions each.

The questions can be anything.  You can use them to recap your retreat weekend or just as an icebreaker.

Examples:  "What's your favorite kind of pizza?"

"When was the last time you got your haircut?"

"What do you think of when you hear the word 'daddy'?"
