There are many things that happen in college that you don't expect. Like this: 

That is a banana. Stuck to the wall near the ceiling of one of the elevators. Our reaction went like this, "Um... what is that? and why is it there?" Then there was a lot of laughing. 

 It was there almost all day. We don't know how it got there. You always have to stay on your toes around here.
