With "Suicide Squad" around the corner and Jared Leto's Joker making quite the stir (have you seen those teeth?), we thought it was about time to find out once and for all: Who is of the best Joker of all time? So, we went straight to the source--uh, sources--to find out, gathering a panel of four Jokers and grilling them on the hot button issues, moderated by the only man who can keep them under control (kind of): Batman.

Drawing together Jokers from across time and space, we were able to wrangle Jack Nicholson's Jokers, Heath Ledger's Joker, Mark Hamill's Joker and, of course, Jared Leto's tattoo-laden Joker. Before the greatest Joker of all time is determined, Batman will need to collect the evidence (he is the world's greatest detective, after all), like which Joker is the best at preparing his diabolical schemes, and which one just most looks the part.

Considering this is a room full of the sinister clowns, the proceedings don't exactly go as planned. But we do get a glimpse into the future, with a prognostication of Joker casting yet-to-come!
