Welcome to Your Daily Nerd Thing where every weekday we bring you a different nerdy thing we found on the internet. The new season of Fall television has begun and all of the CW superhero shows are starting up again. That means soon it will be time for their yearly crossover event. This time they are doing Elseworlds, which has been the DC What If style of stories. This promotional poster was tweeted by Stephen Amell who usually plays Green Arrow. But it looks like during the event we will see a world where he is Barry Allen. Meanwhile our usual Flash actor Grant Gustin will become Green Arrow. I have to admit this is blowing my mind a little.
