It's still fun to mess with the younger nurses....
Nurse: "I need you to do something about this blood sugar."
Me: "I'm not talking to you while you have that parasite growing in you."
Nurse: "My baby is not a parasite!"
Me: "It's growing inside you, right?"
Me: "And it's stealing nutrients from you to feed itself..."
Me: "...and tweaking your hormones to make you think you love it. And after it's 'born' *air quotes*, you'll continue to feed it from glands in your body."
Nurse: "I have noticed my boobs getting bigger."
Me: "And it's not a parasite?"
Nurse: "Damn it. I'm having a tapeworm, aren't I?"
