This bloke decided to tweet that his genetics teacher 'is a faggot'. Aw. What a lovely young gentleman.
Luckily, this is the Internet we're talking about here. Information is incredibly easily to access. And his genetics teacher found out.
Check out his response...
Since then, Professor Eric Mendenhall has accumulated 21k favourite and a tasty 17k retweets. Well deserved.
And people were loving him for it.
