Alright I asked my co-worker tonight what he would do if he came face to face with a rhino and as it turns out he did! This is his story...
"So I came out of [my workplace] and there he was, a rhino! I was like what's going on? and the rhino took out a knife and said to me, 'Hey! give me your wallet!' And I was like, 'No, I'm not going to give you my wallet!' Then he dropped the knife and charged my ass. When he charged me I swung with my right arm and first hit knocked off his horn. When I did he said, 'Ow! My nose!' I then came back with a left and hit him in the jaw and knocked his ass out. I got in my car and sped off and called the police but didn't give them my name. The cops came and the rhino was all like, 'Hey what the Hell! Let me go!'"
True story.
