C: Mama! Did you know, Rhino horns are made out of fingernails?
M: Um, well, no, that's not quite right. Rhino horns are just made from the same thing AS fingernails. They grow on the Rhino's head like your fingernails grow on your fingers.
C: No! Their horns are Made. From. Fingernails! It's true.
M: Nooo... They just grow, their horns grow like really, really thick fingernails.
C: You're wrong! I learned it on a SHOW!
M: But, I mean, how would Rhinos even get fingernails to make horns with?
C: They take them from dead people. That's why nobody is afraid of having Rhinos steal their fingernails, because they only get them from dead people who don't need them anymore. Rhinos are sneaky. They know when people die. They take all the dead people's fingernails off and [hand gestures] boop! boop! boop! they make their horns.
C: It's TRUE.
M: Well, I'm glad you've got it all figured out.
