She Said I Look Like an Earthling

Are you sure you're not from Earth? I'm sure. How about you think about it again? I miss your sister! Your sister is me, what use do you think I have, otherwise if you accidentally fall down and hit your head on a pillar or something, you might wake up. Why don't you let me get kicked in the head by a donkey? Look, you even know this joke, and you still say that you are not an earth traveler!
