No biggie. The next morning I brought in super glue from home, and carefully put it back together. Pissy walked in just as I was finishing up.
Dr. Pissy: "What are you working on?"
Dr. Grumpy: "The C-spine model. I accidentally broke a vertebrae, and had to glue it back."
Dr. Pissy: "Where?"
Dr. Grumpy: "Right here" (points to part of model) "It snapped off when it hit the floor."
Dr. Pissy: "Looks good. I can't even see the crack."
Dr. Grumpy: "Yeah, it was easy. I can't believe they pay neurosurgeons so much to do this."
