You may now stop reading super-hero comic books for all time, because no panel could ever be more awesome than this one. You have won the comics industry.

But as the commenter pointed out, “Captain America, I command you to WANK!” is in fact why I brought it here. It may be the greatest command ever given by a super-villain.
