Roger Greenberg: Wish it wasn't too late to get my medical degree.
Ivan Schrank: It's not too late.
Roger Greenberg: I'd be over 50 by the time I graduated.
Ivan Schrank: What is it? Four years, right?

Ivan Schrank: I'm confused. Are you going to vet school or regular medical school?
Roger Greenberg: Neither, clearly.
