Doppelganger

*Today was the first day where my new classes saw one of my instructional videos.*

Student: "Wait, is that you?" (It is very clearly my face projected up on the wall)

Me: "Nope, it is just some other person who looks exactly like me, also teaches math, and has that exact same chalkboard."


*Ten minutes later*

Student: "No way, that has to be you. It sounds exactly like you."
