Man, there are some clever people out there.
Strack, Martin & Stepper's test of the hypothesis[edithttp://en.wikipedia.org/w/index.php?title=Facial_feedback_hypothesis&action=edit§ion=4 ] http://en.wikipedia.org/wiki/File:Orbicularis_oris.jpg http://en.wikipedia.org/wiki/File:Orbicularis_oris.jpg Orbicularis oris muscle
In an attempt to provide a clear assessment of the theory that a purely physical facial change, involving only certain facial muscles, can result in an emotion, Strack, Martin, & Stepper (1988) devised a cover story that would ensure the participants adopt the desired facial posing without being able to perceive either the corresponding emotion or the researchers' real motive. Told they were taking part in a study to determine the difficulty for people without the use of their hands or arms to accomplish certain tasks, participants held a pen in their mouth in one of three ways. The Lip position would contract the orbicularis oris musclehttp://en.wikipedia.org/wiki/Orbicularis_oris_muscle, resulting in a frown. The Teeth position would cause the zygomaticus majorhttp://en.wikipedia.org/wiki/Zygomaticus_major_muscle or the risorius muscle http://en.wikipedia.org/wiki/Risorius_muscle, resulting in a smile. The control grouphttp://en.wikipedia.org/wiki/Control_group would hold the pen in their nondominant hand. All had to fill a questionnaire in that position and rate the difficulty involved. The last task, which was the real objective of the test, was the subjective rating of the funniness of a cartoon. The test differed from previous methods in that there were no emotional states to emulate, dissimulate or exaggerate. As predicted, participants in the Teeth condition reported significantly higher amusement ratings than those in the Lips condition. The cover story and the procedure were found to be very successful at initiating the required contraction of the muscles without arising suspicion, 'cognitive interpretation of the facial action,[10]http://en.wikipedia.org/wiki/Facial_feedback_hypothesis#cite_note-10 and avoiding significant demand http://en.wikipedia.org/wiki/Demand_effect and order effectshttp://en.wikipedia.org/w/index.php?title=Order_effects&action=edit&redlink=1. It has been suggested that more effort may be involved in holding a pen with the lips compared with the teeth.[11]http://en.wikipedia.org/wiki/Facial_feedback_hypothesis#cite_note-11 However, it has resolved many of the methodological issues associated with the facial feedback hypothesis. Darwin's theory can be demonstrated, and the moderate, yet significant effect of this theory of emotions opens the door to new research on the "multiple and nonmutually exclusive plausible mechanisms"[12]http://en.wikipedia.org/wiki/Facial_feedback_hypothesis#cite_note-12 of the effects of facial activity on emotions.

Apparently Darwin and James had a theory that emotion is caused largely by the feeling of facial expressions. The theories are confirmed by recent experiments with artificially induced facial expressions and with people with reduced ability to produce facial expressions due to Botox.
