SPOILER ALERT: This is not a scene from Batman v Superman: Dawn of Justice. No matter how hard we wish it was. No matter how many rumors we try to start about and exclusive Ukulele/Bagpige rated Blu-ray edition.
This is simply the work of the YouTuber known as The Unipiper and we thank him for it.
(Personal note to my wife. When I die. I want Superman playing flame throwing bagpipes while riding unicycle to see me off to my final reward. Ukulele Batman is optional Thank you.)
