In the commentary for the episode, Jeff Eastin (creator of the show) mentions there was a prank script sent to Willie Garson about Mozzie's fate in the clinic. In the prank script, Mozzie gets lobotomized and the end of the episode is Mozzie in a wheelchair while Neal and June cry in the background. Jeff Eastin says he never heard back from Willie, so he's not sure if he read it or just was going to accept it.
