''World's Funniest is considered non-canon simply because when DC published a lit of "Elseworlds" comics, Superman/ Batman World's funniest was one of them and its well known that any and all Elseworlds comics are not cannon (although few wiki tend to say its cannon, which is weird + add to the fact that even Flashpoint is listed as being Elseworld). Also during his interview Evan Dorkin stated that when he wrote Worlds Funniest he specifically asked for it do be drawn like Pre-crisis, i do not how much that weight towards being non-cannon but thats one thing. Furthermore, the same comics establish the anti-life equation to be Mr. Mxy + Batmite, which we know to be untrue.''
