They really are running out of ideas.
This type of plot was done. TWICE.
First with James Woods (which was pretty funny, actually)
Then with Jesus (I think you guys liked that one)
Now, it's O.J. Simpson, who is, by the way, in jail right now, so the timing couldn't be any more...what's the word? Oh, whatever.
EDIT: Make that a 4th time, forgot to include Bill Clinton.
