Get the No cappermug. Humanity’s greatest failure, Capper is a slimy, disgusting freak of nature. The only thing more disgusting than his deformed kneecaps, is his blemished, repulsive face. He seems to think that he is the greatest human, however everyone laughs at his pathetic existence behind his back. Jesus did not die for inbred rats like capper.
Capper is a disgusting thing
