Well, I think that it symbolizes the rote nature of so-called "comedies" that blight our cinemas today, utilizing tired old gags and jokes to amuse the plebeian masses who cannot appreciate true art. The rubber chicken, which was once the height of comedy and is now so overused and outdated as to no longer even exist in the comedian's repertoire, lies limp as if dead to represent this sad state of affairs. *puts pipe in mouth for dramatic emphasis*

LOL OMG ITS A RUBBER CHICKEN

I think it worked.

braaaaaaaaaaaaaaaaaaawk

Perhaps it is symbolism that is the rubber chicken.

boom.

So, subtlety is your goal?
