Send it to a few people and we can each voice a character, make a podcast of it.
Will need some audio editing software...
Remember a sitcom is "situational comedy", shows like Seinfeld and Friends worked so well because they created funny yet relatable situations which is unfortunately is at odds with your exotic characters, but that juxtaposition itself could be funny, e.g. Someone explains the birds and the bees to the xenomorph and he's horrified by it, "So you're saying they reproduce by touching their..." (343) "Not just touching, the male inserts-" "STOP! Eww no shut up I don' to want to hear this, my god humans are disgusting", and for added drama/comedy the Xenomorph is in a romantic relationship with Light who may or may not be gay since a xenomorph drone is neither gender.
Exotic characters + normal people problems (more or less) = funny.
