Follow the Leader, But Don’t Be A Lemming

From Wikipedia:

Follow the leader is a children’s game. First a leader or “head of the line” is chosen, then the children all line up behind the leader. The leader then moves around and all the children have to mimic the leader’s actions. Any players who fail to follow or do what the leader does are out of the game. The last person standing other than the leader is now the new leader.

Following the leader can be good (i.e. trend following) and bad (i.e. lemming behavior). Lemming? Yes, lemming:
