When I looked up "rubber chicken" at wiseGEEK, I was expecting to read an article about those corporate luncheons I have to attend every week at a local hotel. The main course is always some kind of chicken, since it's the cheapest meat that can feed 250 people at a time. My co-workers jokingly refer to these luncheons as "rubber chicken dinners", because the chicken breast is almost always chewy and barely edible.
I figure the quality of the food at these rubber chicken events is rarely the point. Usually the president of the club invites a guest speaker, and there's often entertainment and a brief business meeting. I've been to a few rubber chicken dinners for political candidates, too.
