I noticed that you just changed up your nephew's diaper. Shouldn't you wash your hands.
No! I have an Immune System, so I don't need to wash my hands.
While it's true that your Immune System is your body's best defender, common sense measures such as hygiene, exercise, and routine vaccination can help your Immune System do its job by decreasing its workload or giving it samples of pathogens so that it can recognize them later.
Nah! My doctor says that's baloney!
What kind of doctor says that?
I failed, he's yours now.
Dr. Bruce Banner! I did not expect to see you here!
I Thor, Odinson, have the wrong hammer! LOKI!!!!!
