Did not think of popeye but when I seen the title I was thinking it was going to be a picture of the Green Giant or the little giant that was in those old tv ads.
That would be Sprout, I believe. And unless the Giant or Sprout are cannibals, I figure they would be immune. Unless, of course, it's transmitted through the skin...or peel, whatever.
And technically, Popeye always ate out of a can....
