MMI Scenario Commonalites?

For those that have been to MMIs in the past, do schools ever use very similar scenarios to the common "practice ones" you see online (birth control, jehovah witness, alternative medicine, organ donation, etc), or at least ones with similar themes? Has anyone been hit with a scenario completely out of left field (excluding traditional interview questions)?
