Being looked at like I'm stupid

Welcome to Friday Saturday Photo, a new feature where I share photos that I've taken with the world.

Yea, I know, I forgot to do this yesterday. Well I'm doing it now so quityerbitchin.

The other day I was discussing the principles of quantum physics with someone when Petey came in. His look is just priceless:

Huh?

Don't worry Petey, most people feel that way about it.

Including me, considering I had to type quantum physics into Wikipedia just to see what it is and that was all I could think after reading the first paragraph.
