Bio: Mitcham won gold at the 2008 Olympics. When fellow Australian Olympians Russell and Lauryn Mark of the shooting team complained that they couldn't stay together in the Olympic village, saying it was anti-heterosexual descrimination and that gay couples could stay together, Mitcham spoke out against them on Twitter. "Since there were only 11 out gays across all nations [in 2008], I’d hardly consider that a ton. Known couples are split anyway." He followed it up with, "The last thing I need is a sexually frustrated breeder with a shotgun being cross with me. No comment, thank you very much!!" So he's pretty funny. Also he loves memes.
