It was a relatively quiet morning at the watchtower. That is until flash came because, 34 seconds later a thanagarian war cry was heard throughout the tower. Flash was seen running through the halls yelling "April Fools" as shouts of anger echoed through the halls. Heroes started to gather in the monitor womb with pink wings and green hair. Batman watch this all from his dark corner he saw Shayera's wings were dyed a bright pink and superman was tearing out his hair because it was dyed green. Green lantern was glued to several bright yellow rubber duckies and J'onn was holding a package of plastic oreos unamused at the prank. While watching these proceedings, Batman was preoccupied with outrageous sight. When speedster with a love to annoy, ran up at about the light speed of light and picked him up. then dropped him in the cafeteria behind Wonder Woman and before he could stop Flash he was covered in pink with red heart duct tape. That bound him and Wonder Woman in a very awkward position. Then , when Wonder Woman tried to escape the duct tape pushing out with her arms batman was pressed tighter into her back causing them both to blush though neither of them would admit it .
That is why the Justice League was hunting the Flash.
