1, Wow, are you a worm in my stomach? Then you must help me digest the food and don't get me pregnant!
2. Haha, are you a tapeworm? Then you must be ready to put on a wonderful roundworm song and dance show in my stomach!
Oh, I don't want to keep ascaris as a pet. You should stay in my belly and don't cause any trouble! Remember not to eat all my food!
