I suggest a butt challenge! Buttocks in all their (preferably naked, preferably buff) glory! They're a great place to be shot, receive a "manly" swat, or they could be red from spanking (okay, Ces, I admit, I want the challenge because I'm hoping someone will write a good spanking scene. Help a girl out! *g*) And also, for those who don't like to be limited, you could have the 'butt' of a joke, the 'butt' of a gun, someone needing to 'butt' the heck out of John and Rodney's kinky spanking sex life...

(Yes, I intentionally chose an icon with a picture of a butt. Do you see my commitment to this theme?)
