April Fool’s Day jokes are generally supposed to be fun and harmless, but this zombie prank on a subway prank in Portugal was anything but.

There was far too much effort put into this thing – it’s pulled off in the perfect setting with dozens of actors in perfect makeup and costumes – to make it a harmless joke. This kind of execution can only end with victims being scarred for life.

You really can’t convince me that all of these people won’t have an irrational fear of subways for the rest of their days. That’s just mean.
