This is one of the reasons I don't want to become a large animal vet.
When I was trying to measure the heart rate, the cow decided to eat. All I heard was CHOMP CHOMP MUNCH MUNCH OM NOM NOM GULP.
When I was concentrating on finding the heart sound, the cow next to me decided to get close.....very close.... for some reason.
And then suddenly, Tiger Cow sandwich.
In reality, I moved out in time. However that wouldn't be funny if I draw that in a comic, right?
See the thing that looked like mud?
it's not mud.
