"just this January, Maxim commissioned copulating bunnies, each made out of a hundred-dollar bill. Like a makeup artist, [Marc Kirschenbaum] was on standby as they shot the scene. He had just a single touch-up; one of the bunny's ears had come slightly undone."
From the article JMcK linked to. (for those of you who are too young and/or squeamish to view a little "pornigami"[sic])
That could have been me...I corresponded with the lady at Maxim, but I forgot to send the fornicating bunnies photos... (would have made me quite a hit at my college though

)
