Just go on the 2f2f Mario_Kart server and type !<insert class here> alone or with another !class into the chat thing. The server was quiet for awhile (the first time it was on there, I guess), and everyone was typing some combination of the !class. I wondered what it was all about, so I treated myself to a "splendid" view of the Medic fondling his own hoo-ha. "Oh. Porn," was all I could manage.
