Don't you want to be a citizen of El Shelvador?

Study this picture closely. The woman on the left is making a gesture often found in illustrations & movies, but did anyone actually do this? Clasp their hands and shove them into their neck? The only authentic posture is the man, who has his hands in his pockets in the traditional pose of we'll-wait-and-see reserve, but clearly is enthused by the flame-haired tiger lady demonstrating the Shelvador.
