Look: I have read a lot of weird old DC comics. It's kind of my thing. But the great thing about them is that no matter how crazy they get, every time I think I've seen the weirdest thing that comics have to offer, they always somehow manage to top themselves. Case in point: a Cary Bates/Ross Andru/Mike Esposito classic from 1968 that has somehow managed to outdo every other comic I have ever read. I realize I say this all the time, but this is, without question, the absolute balls-out craziest comic I have ever read.
Seriously, folks, I'll go ahead and tell you right now that Batman casually mentions owning a time machine in this one, and as far as weird stuff goes, that's not even in the top five.
