Suppose you felt your diaphragm and throat move in such a way that the resulting sound sounded like laughter, but you did not experience the least happiness (a bit like people who can suddenly find themselves crying without having any affection). In that case it would seem likely just the motoric parts of expressing happiness were active, and upstream happiness functions (like a positive mood) not involved. Of course, there is a certain amount of feedback so being forced to laugh for a while might make you happier, but at least initially there ought to be a noticeable difference which would help delineate how the happiness system works.

Do you usually choose to laugh? Of course, the devil lurks in the details of "you" and "choose" - these are high-level descriptions of what is going on, and have little to do with reality.

My experience is that it is common, but less common among people involved in neuroscience. However, many seem to cloak themselves in it when speaking with the public, since the emerging truth (a mind consisting of highly interactive parts with no center and no correspondence to the classic ideas) is so hard to swallow for many.
