The things I spend my time doing all day

Today I am going to spend time with my arm up a cow's rectum while I try to wiggle a tiny little metal rod through her cervix to deposit an embryo inside a certain horn of her uterus. You gotta love modern technology. It's called Embryo Transfer (ET for short) and it's really cool. The downside? You have to thread something you can't see into something you can't feel and pass the various obstacles that present themselves. Cool, huh? :)
