Obama plays Obama on SNL

New York -- U.S. Democratic presidential hopeful Barack Obama appeared as a surprise guest on NBC's "Saturday Night Live."

Cast members spoofed the Democratic presidential pool with a mock Halloween party hosted by Obama rival Sen. Hillary Clinton, D-N.Y., The Los Angeles Times said Sunday.

A late arrival showed up wearing an Obama mask, who turned out to be the Illinois Democrat himself, The Times said.

The actress portraying Clinton questioned the costume and Obama replied:

"I have nothing to hide. I enjoy being myself. I'm not going to change who I am just because it's Halloween."
