Do the images in Firefly Fun House mean anything?

Is there a deep meaning to the images in Firefly Fun House? Maybe this has been known for a while and I'm behind, but what's the story? The Muscleman Dance and Huskus, does this represent Vince telling Wyatt during his Husky Harris days that he needed to lose weight? Does it represent Vince being obsessed with big (muscular big) workers? And then you have the reptilians, obviously there are actual conspiracy theorists like David Icke who think reptilian aliens run the world. I know Vince appears with devil horns every so often.

So my main question...does it all mean something, or are they just silly images popping up?
