Just look at that Nick Fury. His trademark eye patch. His muscular torso. His oddly positioned running-in-space pose. And his traditional half-smoked cigar enjoyed from within his freaking space helmet!
I suppose it’s maybe not dangerous because it isn’t lit, but then why would it have a full inch of ash on the end? I suppose it’s possible that Fury is dumber than a box of sticks to put on his helmet that way, but doesn’t that seem unlikely for a man of international intrigue?
No, the more likely explanation is his once hidden love of autoerotic asphyxiation. Note that the expression on his face isn’t a grimace of discomfort. No, good ol’ Nick is smiling as that last whiff of oxygen is replaced with a mind-blowing happy ending. What a sicko.
