BB pal Vann Hall suggests these two unrelated possibilities as the greatest Batman panels of all time. I like these, but I'm partial to "Batman does BDSM." Click the images above to see the panels larger. Vann writes:
I know: It's a tough call, given how many contain un[?]intentionally lewd or homophilic references -- I especially love the whole episode about the Joker "pulling a boner" but I think Joe Cannon might just be right about this illustration of Robin being taught the facts of life. The other panel is a long-time favorite of mine, and a possible contender for the throne.
