I’m not really sure why, but that one puzzle from Brooklyn 99 S02E18 popped back into my head today.

There are 12 men on an island. 11 weigh exactly the same amount, but one of them is slightly lighter or heavier. You must figure out which.

The island has no scales, but there is a seesaw. You can only use it three times.

And also, you must determine whether the odd man is lighter or heavier.

Can you figure it out?
