knowyourmeme.com/memes/y-u-no-…knowyourmeme.com/memes/eddy-sh…Damn it, both pictures became memes in the same year. But I think Eddy's pose and expression is from a 1999 episode, so it's older than the face from the manga (2002) which became more famous.
I assume that the similarity between both expressions is accidental.
