Overheard in the Classroom ... Deja Vu Edition

This whole HPV vaccine is all the conversational rage these days ..... one kid had gotten it (the vaccine, NOT the disease), so someone else was asking her if it hurt or anything like that.

Questioning Student [turning suddenly to the teacher]: Sr. Steph Umm, I mean Madame Teacher Nun^*, have you gotten the vaccine yet?
Madame Teacher Nun [thinking nothing of the question]: No.
Neighbor of Questioning Student [with a very strong "What kind of a stupid idiot are you?" tone]: She doesn't need that — she's a NUN!
