There’s the smallest of chances that Eddie Murphy will make an appearance on Saturday Night Live this weekend, according to “Page Six.†Ben Stiller is hosting, and he and Murphy co-star in Tower Heist, so there’s a moment of could-be promotional synergy there — especially since Brett Ratner directed the movie and is producing the Murphy-hosted Oscars in a few months. Murphy hasn’t appeared on SNL since he left the show in 1984 (even in a cameo), nor did he contribute to Live From New York in 2002, so if he did swing by, it would be A Thing. [Page Six/NYP]
