Me: wait, sharks have live young?
Tom: yeah
Me: but they aren’t mammals
Tom: no
Me: but they have live young?
Tom: think about what being a mammal means
Me: right so…are they mammals?
Tom: seriously? You majored in dairy science and you don’t know if a shark is a mammal?
Me: dairy science, not shark science

You guys it is totally blowing my mind that sharks have live young so I’m telling everyone I know. Did you know that sharks have live young? Thank goodness for shark week I had no idea.
