Professor or Hobo?
Can you tell the difference between a Professor and a hobo? Joseph Somody has posted a quiz. Check it out: Professor or Hobo?.
Joseph is the undergraduate winner of Monday's Molecule #147. I'll be having lunch with him on Wednesday. If you have any other pictures of professors or hobos, you could post a link in the comments and I'll be sure to pass them long. (Joseph will probably read them anyway.)
I'm thinking we could do a similar quiz for students—something along the lines of "university student or not?" There are plenty of pictures on facebook that professors could use.
