Hayley Roll, a radiology technician at Cincinnati Children's Hospital, and Nick Kelble, a student at the University of Cincinnati, were at the Cincinnati Zoo on October 8th, waiting in line to see Fiona the hippo.

Nobody at the zoo knew about what was about to happen, so Fiona's appearance was totally on her own - Nick got down on one knee and proposed to Hayley, and the little hippo was right there for the moment. And the photo is PRICELESS.

Of course, she said yes. And she captioned her Instagram picture with:
