Scene: a spaceship. A human and an alien are chatting over a cup of hot chocolate/brine. It is the first time the alien has ever mixed with humans.
Human: “So yeah, I slipped and Brad just started laughing like an asshole and…”
Alien: “Sorry, what?! Can you repeat that? I think my translator is broken.”
Human: “I said I slipped and Brad started laughing his stupid head off like the asshole he is!”
Alien: (takes translator off, checks it, puts it back on.) “Oh my [untranslatable, deity associated with surprise and sulphuric acid] you actually meant to say that!”
The two of them stare at each other, the human in confusion, the alien in straight up horror.
Alien: “… your species, your anuses can… laugh?”
