For those who don't know, Corinne Bohrer has been pushing to get on The Flash ever since the show started. With this post, she's strongly hinting she succeeded. In a strange bit of prophecy, Mark Hamill played the Joker-like Prankster on the original 1990 show. He even had a Harley Quinn before Harley was even a thing, named "Prank," and that was who Bohrer played. Hamill has reprised the Prankster on the CW Flash two or three times now, and Bohrer's been like "Where's my part?" Like Harley, Prank is nutty, insane and unhinged. It's not Winnie but it's as close as we're gonna get.
