Liberals
Liberals are actually not people. They are actually a rare form of jellyfish. They only appear to look like plotical entities you disagree with because you are seeing things. Please pass the ketchup!!
Thank you. Now, as to the matter of their appearance, they look just like regular people you meet everyday, provided you aren't a hermit or something. The way to identify them is by their soft heads. And by soft, I'm not talking about their outlook - no I mean literally because they're actually jellyfish. Conservatives, on the other hand, are hard headed - so hard headed that you need one of those hammer and sickle things to make their heads explode.
But I digress. Places where you can find liberals include college campuses, government buildings, unemployment offices, welfare lines, abortion clinics and zoos.
