Is there a small group of your characters (from two to five) that tend to “share the brain cell”, as the colloquialism goes - that is, they tend to do stupid things for fun when hanging out together? Is there any one person in the group that has the singular “brain cell” more often than anyone else - that is, they have the most sense in the group, and tend to act upon it?

Bonus: Are the people in this group normally very smart when they’re not hanging out, and they just get stupid when brought together?
