It is one of the most hilarious and popular memes to come out of the Arrowverse - the behind-the-scenes photo of Grant Gustin as Barry Allen standing next to the grave of Oliver Queen/Green Arrow while smiling and flashing a peace sign during the filming of the final installment of "Crisis on Infinite Earths". Since it was originally shared, that photo has been turned into a meme about almost anything and on Monday, when Facebook and its associated apps and services went down in a massive outage, fans on social media did their thing by bringing the meme back into service and Arrow star Stephen Amell has something to say about it. On Twitter, one of the few major social media platforms up and running on Monday, Amell shared one user's take on the meme with the grave featuring the icons for WhatsApp, Instagram, and Facebook, while Grant Gustin's face was replaced with the Twitter logo. It's pretty funny, the idea that Twitter is "celebrating" being the last man standing as it were, but Amell might not have seen the humor in it.
