Your Knowledge Of Diseases Is Rusty

(My sister and I are at a hair salon, and while getting our haircuts the topic of plucking eyebrows came up. My sister’s have just been waxed.)

Sister: “My eyebrows look better than yours now!”

Me: “Yeah, because they were just done by a professional. I do mine in my bathroom with rusty tweezers.”

Sister: “Rusty?”

Me: “It’s not too bad. I haven’t gotten tetanus yet so I guess I’m okay.”

Sister: “What’s tetanus?”

Me: “It’s what you get when you cut yourself on something rusty.”

Sister: “I thought that was polio!”

Me: “…Polio?”

Sister: “Polio is what you get when you cut yourself on something rusty!”

Me: “No, it’s tetanus!”

Sister: “What does polio do then?”

Me: “I don’t know; make it so you can’t walk? That’s why FDR needed a wheelchair. He got polio.”

Sister: “Wait, if you get tetanus from rusty metal, then what did Jonas Salk cure?”

Me: “POLIO! And he didn’t cure it, he created vaccines for it!”

Sister: “So who cured tetanus?”

Me: *groans*

(She did eventually get it. But how you can make it to 20 thinking you got polio from rusty metal is beyond me.)
