Comic books are one of the easiest places to find out of context comedy because all panels in the book relate to each other, so if you isolate one panel from the rest it reads as totally bizarro.
Sometimes you can even isolate a cluster of panels and they will still read as sick and twisted, even if the tale being told takes place in squeaky clean Riverdale High.
Of course, there are plenty of strange panels lurking around in old comics that don't need any help to tickle a reader's funny bone
But remember- all of these panels were taken from kid-friendly comics, so any perversity you perceive is just a product of your naughty imagination!
