It's the obvious next step.
I propose Diana Ross in place of Paula Abdul (the pun possibilities are just too endless), Joe the Plumber in place of Randy Jackson (both balding and a little on the plump side), and Clive Stafford Smith in place of Simon Cowell (as the token Brit - just get him to pull his belt up a little more, and no-one will tell the difference). I see 'American Idol' now has a fourth judge - just bring her straight over, to pull in the existing fans. I'm sure she has excellent views on judges from the previous program anyway.
Then we get the contestants to rerun old 'Judge Judy' decisions, 'Law and Order' episodes, and dance with a computer-generated baby in a unisex bathroom. This gives a good overall view of the American legal system, I feel.
All we need is a snappy title. "I'll Be the Judge of That!"? "The Supreme Sacrifice" (maybe just for the early auditions, when there are lots of no-hopers for everyone to laugh at and humiliate publicly)? "Court in the Act"? Or "Act in the Court"?
Suggestions on a postcard, please.
