Polar Fox: Dude, did you get any permission to use a trademark?
Red Fox: What permission? This is a public service we are engaged in.
Polar Fox: Oh really? Still I say that logo has an owner. It says in its corner, see.
Red Fox: Go ahead; let those capitalist scumbags know about it.
Polar Fox: Oh come on Red, stop acting like a mild Chávesian socialist. You spent all your time in youtube and facebook.
Red Fox: Yeah, I am extending my base in the internet for a revolution.
Polar Fox: Yeah, sure. The only thing I see revolving is your chubby belly.
