Are you a fish?

Kid: I don't feel good. I have a cold.
Me: You've lounged around all weekend. Eat something. You're fine.
Kid: I'm not fine. I feel oogey.
Me: Tough. You don't have a fever. Eat something and go to school.
Kid: It's awful. I think I could be dying.
Me: Let's take your temperature
Two minutes pass....
Kid: Look it says I have a fever.
Me: Huh? Really? What does it say?
Kid: 97.5. I told you I was sick.
Me: You don't have a fever and you must have done it wrong. Either that or you're an amphibian.
Kid: No. Human temperature is 96 something.
Me: That would be 98.6- that is the normal human temperature.
Kid: Oh.
Me: Off you go!
